The existence of solar systems other than our own (extra-solar planets). What properties of our solar system must a formation theory explain? Module 3 Lab 6: Formation of the Solar SystemLearning Objective: You will explore the processes/steps of solar system formation and identify which process/step leads to the characteristic we see today. The Sun formed about 4.6 billion years ago in a giant, spinning cloud of gas and dust called the solar nebula. E.g. Common ages of 4.6 billion years for Earth, moon Mars, meteorites and the sun. Stages of Star System Formation Starting point: A cloud of interstellar gas and dust, the "solar nebula"; Most of it (98%) is hydrogen and helium, but it includes atoms and dust grains of heavier material, formed in previous generations of stars. Origin of the Elements, the Solar System and the Planets. If the compression raises the core . Simulating Solar System Formation. 3.8 to 3.5 billion years ago: Life begins on Earth. As per the Capture theory, the age of sun is . The field is carried through the solar system by the solar wind - a stream of electrically charged gas blowing outward . Download the Planet Sort worksheet . The right classroom resources help you . Planetesimals accrete into protoplanets 4. The hydrogen protons began fusing, forming helium and releasing massive amounts of energy. A cloud of gas and dust in space is called a "nebula". The initial collapse is supposed to take . The solar system as we know it began life as a vast, swirling cloud of gas and dust, twisting through the universe without direction or form. As the cloud collapses, it heats up and compresses in the center. Broadly, four stages can be identified in the process of planetary formation. 5 billion years ago the sun formed from a cloud of gas and dust that collapsed because of gravity. As an example, consider the solar system. Solar system formation in two steps. Planetary systems form around new stars. "The Earth used to look just like that." Terms in this set (5) Step 1 of the formation of the solar system. Ðsmall, rocky terrestrial planets . This collapsed under its own gravity, transferring gravitational potential . What are the steps in solar system formation? These two features are clues to how the solar system formed. What are the steps in solar system formation? Describe the formation of a star/solar system in a series of steps. Eventually the pressure at the center raised the temperature so that hydrogen atoms fused . rotating protostellar disk. As it contracts, it spins faster and faster, much like an ice skater who pulls in her arms. "The bottom line is, everything that happened on the moon happened on the Earth," said David Kring, crater expert and team leader for Center for Lunar Science and Exploration. Step 2 of the formation of the solar system. Each planet rotates on its own axis while revolving around the Sun. Our solar system is home to Earth and seven other planets. Step 3 of the formation of the solar system. 7. Formation of the Solar System. 1. This theory mentioned that, 4.6 billion years ago, the Solar System was formed by the gravitational collapse of a giant molecular cloud spanning several light-years. The Solar System was formed around 4.6 billion years ago from a large cloud of dust and gas, called a nebula. Terrestrial Planets form 5. This explosion made waves in space which squeezed the cloud of gas and dust. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. Formation or organization of. The Sun keeps this complex arrangement in order. Planetesimals begin to migrate, orbit, and move around through the Solar System. All solar systems start out the same way. Formation. Unformatted text preview: AY 101 Class Notes Test 2 Chapter 6: Formation of the Solar System What are the major features of the Sun and the planets? About 4.6 billion years ago, this gigantic cloud was transformed into our Sun. Without these elements there would be no Solar System . They are made up of mostly hydrogen but also contain other matter like gases, dust, ice and rock. Step 3 of the formation of the solar system. Saturn came a few hundred thousand years after that, and Neptune and Uranus (that was the order at the time) came sometime after that. This material formed a. Rocky planets, like Earth, formed near the Sun, because icy and gaseous material couldn't survive close to all that heat. The 6 stages of formation are: 1. the main stages in the formation of the Solar System (pg. Gas Giants Form 6. This led to the formation of the star that is the center point of our solar system—the sun—roughly 4.6 billion years ago. "There is a rotationally . A dense hydrogen-rich cloud of gas and dust contracts under gravity. As the sun was forming, it collected almost all of the solar system's material. Formation of the Solar System Reading: Chapter 9 ¥Quiz#2 Today: Lecture 60 minutes, then quiz 20 minutes. We believe the early solar system was a cold cloud of interstellar gas that had a fairly fast rotation so not all of the gas could fall into the star forming at the center. . All things with mass come together, or gravitate towards one another. 4 to 3 billion years ago: Small world bombardment causes widespread volcanism on the inner planets. Formed by gravity into a large molecular cloud. The gravitational collapse of a star leads to the formation of a core to the gas cloud and the formation of a huge rotating disc of gas and dust, which develops around the gas core. the solar nebula collapses. The solar system is made up of some major and minor players, all of which interact with each other. Arrange the steps to model the formation of planets. The planets, moons, asteroids and everything else in the solar system formed from the small fraction of material in the region that wasn't incorporated in the young sun. Step 2 of the formation of the solar system. What is the explanation of the solar system diagram? Make sure you fully understand what causes the solar nebula to go from one step to the next. Gas and icy stuff collected further away, creating the gas and ice giants. All the planets orbit in the same direction around the Sun. Patterns of motion of the large bodies • Orbit in same direction and plane 2. The solar system features a unique dichotomy of planets -- the inner solar system features smaller, drier bodies, while the planets found in the outer solar system are larger and wetter. The mysterious lack of angular momentum of the sun 10. Question: 6. Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. Second Step: The clouds so formed are gravitationally unstable, so the conservation of angular momentum on these compresses and reshapes the cloud into a . Early Hypotheses The Solar Nebula Hypothesis Solar Nebula Theory Continued Formation of the Solar System Planet Formation - Accretion Planetesimals forming planets Evidence for Ongoing Planet Formation . All the planets lie in nearly the same plane, or flat disk like region. Every planet has unique characteristics and qualities that set it apart from the rest. Scientists believe that the solar system was formed when a cloud of gas and dust in space was disturbed, maybe by the explosion of a nearby star (called a supernova ). As the gas gets compressed, its temperature increases and the dust. Make sure you fully understand what causes the solar nebula to go from one step to the next. There are still leftover remains of the early days though. [1] Composition of solar exterior Nebular Theory: Our solar system evolved from a contracting nebula. If the compression raises the core . The solar system is the sun and all the bodies that revolve around it. Our solar system formed about 4.6 billion years ago. 6-12 Pocket Solar System. They are made up of mostly hydrogen but also contain other matter like gases, dust, ice and rock. Our Solar System, and all other star systems, form from a collapsing nebula. Existence of two types of planets • Terrestrial and jovian 3. 4)Heat from the sun . NASA sent . Often called stellar nurseries, nebulae are the birthplace of stars. Planetesimals collide and some stick together. The formation and evolution of the Solar System describes how the Solar System began, and how it changed.. About 4.6 billion years ago, there was a large cloud of gas nearby our area of space. 60 Fe cannot be produced by intense, energetic solar radiation, so it must have been made before the Solar System began to form. Gravity. The paper presents a new theoretical framework for the formation and structure of the Solar System that can explain several key features of the terrestrial planets (like Earth, Venus, and Mars), outer Solar System (like Jupiter), and composition of asteroids and meteorite families.The team's work draws on and connects recent advances in astronomy (namely observations of other solar systems . Planetesimals Form 3. They begin in a cloud of gas and dust called a . Planets of our solar system formed from the material drawn from the protostar. It heats enough for the dust to vaporize. "This world was once a fluid haze of light, Till toward the . A star such as Beta Pictoris shows a central core of this type, with a disc of matter . Excerpted from 2015 PNT (Position, Navigation and Time) Symposium talk, entitled: "Rosetta: To Escort and Land on a Comet" by Fred Jansen, Senior Rosetta Mis. Describe the formation of a star/solar system in a series of steps. Describe the formation of a star/solar system in a series of steps. Nebular Theory: Our solar system evolved from a contracting nebula. A. solar system. 5-6). An artist's concept of what the early solar system looked like, some 4.5 billion years ago. The inner terrestrial protoplanets accrete early, inherit a substantial amount of radioactive 26Al, and hence melt, form iron cores . The remainder of the cloud formed a swirling disk called the solar nebula. There are two additional key features of the solar system: 1. 6. consists of a collection of objects orbiting one or more central stars. […] The sun revolves around planets, asteroids, comets, and other things. Under the influence of its own gravity, the nebula contracts. Other objects are pulled into orbit around the sun. step 2. Our solar system began forming about 4.6 billion years ago within a concentration of interstellar dust and hydrogen gas called a molecular cloud. Small bits of dust and gas . Prerequisites: Read Chapter 8 on Formation of the Solar System in your textbook, watch this video: Materials Required: A computer and internet Keywords: solar system, planet formation, meteorites (Some figures may appear in colour only in the online journal) 1. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. And like that, the solar system as we know it today was formed. the possible dynamical evolution of the solar system since its formation and its future are considered. There are also dwarf planets such as Pluto, dozens of . Solar System Formation. You probably know more than you think you do. The below diagram shows the formation of our solar system, i.e., Nebular Model: First Step: The dust particles get pulled by a self-gravitational force which then condenses to form a cloud. Stage 3 : Hydrogen Fusion Starts. Formation and evolution of the Solar System From Wikipedia, the free encyclopedia Artist's conception of a protoplanetary disk The formation of the Solar System began about 4.6 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. Planets are very tiny compared to the distances between them The Sun is the size of a grapefruit Currently, there are eight major planets with nearly circular orbits orbiting the Sun in the same direction in nearly the same plane Pluto and Eris . The cloud contracted under its own gravity and our proto-Sun formed in the hot dense center. Watch their young eyes fill with wonder as they contemplate the moon and how the earth was created. Under the influence of its own gravity, the nebula contracts. . Click card to see definition . The solar system proves an abundance of learning opportunities. 4.1 to 3.8 billion years ago: The giant planets' orbits shift, scattering small worlds throughout the solar system. The solar system was formed through tidal interactions which took place between a protostar having low density and the sun. In the center, the material clumped together to form a protostar that would eventually become the sun. 6.4Radio Telescopes 6.5Observations outside Earth's Atmosphere 6.6The Future of Large Telescopes Key Terms Summary For Further Exploration Collaborative Group Activities Exercises Review Questions Thought Questions Figuring for Yourself 7Other Worlds: An Introduction to the Solar System Thinking Ahead 7.1Overview of Our Planetary System This effect is known as conservation of angular momentum. The Story of Our Planet's Formation. You can teach about astronomy, physics, or biology. As it contracts, it spins faster and faster, much like an ice skater who pulls in her arms. Process. So, what this theory is saying is as follows: Originally . Formation of the Solar System. In 2007, researchers at the University of California-Davis determined that our Solar System was fully formed at 4.568 billion years ago. 1)started as swirling could of gas and dust called a Nebula 2)Gravity pulled most the matter towards the center and the cloud spun faster. This problem has been solved! The most widely accepted theory of planetary formation is known as the nebular hypothesis. This larger model is based on the solar nebula hypothesis (or nebular hypothesis), initially proposed in the eighteenth century . This was the ignition of Sun's fusion furnace, which is the source of its phenomenal energy output. 9. Describe the formation of a star/solar system in a series of steps. Genesis 1 contradicts the evolutionary history of the universe and life in it at nearly every . 3)Fusion starts... a star is born. strip should show the main steps of how the Solar System formed. The solar nebula is a cloud of interstellar gas and dust that condensed to form the entire solar system, including the sun and planets. Our Solar System, and all other star systems, form from a collapsing nebula. center of nebula fusion begins, star is born. The best bet is that much of it was made during the supernova explosion that triggered the formation of the Solar System. The story of how our Earth was formed 4.5 billion years ago, told from the perspective of an asteroid called Bennu (which has survived until now). Formation. The spin caused the cloud to flatten into a disk like a pancake. Some bombard the inner planets and likely deliver water and organics to Earth. Terms in this set (5) Step 1 of the formation of the solar system. Steps of the formation of a solar system STUDY Flashcards Learn Write Spell Test PLAY Match Gravity Created by doubletroublemaker Terms in this set (5) Step 1 of the formation of the solar system the solar nebula collapses Step 2 of the formation of the solar system rotating protostellar disk Step 3 of the formation of the solar system The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. (1 is first and 6 is last) Condensed materials form planetesimals. Don't take more than 5 minutes to try to figure this out. Formation of the Solar System The revised vision of how asteroids and comets formed came to fit logically and neatly into the larger model scientists had developed to explain the formation of the entire solar system. rotating protostellar disk. Squeezing made the cloud start to collapse, as gravity pulled the gas and . The Sun and the planets and all of the other stuff in our solar system all formed from a really big cloud of gas and dust in space. The Origin of the Solar System. The sun's gravitational pull helped in drawing material from this low-density protostar. The Sun was surrounded by a cloud of gas, dust, and rocky particles that slowly built up protoplanets to become planets, asteroids, and moons. Big Ideas: The phenomenon of planetary system formation serves as a context for the emergence and evolution of life. The moon's surface is riddled with craters ranging in size and structural complexity, and billions of years ago before life emerged, the Earth looked the same way. Our solar system began to form around 5 billion years ago, roughly 8.7 billion years after the Big Bang. center of nebula fusion begins, star is born. NASA. Click card to see definition . The Solar System was a really messy place at this time, with gas and dust and debris floating around. The terrestrial planets formed la. The solar system consists of our sun, which is a star, and all that its gravity affects. September 15, 2016 Our spacecraft have visited rocky asteroids and icy comets to collect invaluable data about the origin of the Solar System. Click again to see term . the solar nebula collapses. ¥Homework#1 will be returned on Thursday. The gravity of the nebula pulls this matter into the centre, and the nebula experiences a gravitational collapse. The formation of planets. There are questions in each box to remind you of the main things. Formation of the solar system How does a solar system form? How many toads are there in the world? The disturbance could be, for example, the shock wave from a nearby supernova. The first stage of planet formation began when dust grains in the solar nebula formed condensation nuclei around which matter began to accumulate. Tap card to see definition . step 1. The Sun. Look at the photos of the different stages in the formation of a planet. At some point, as temperature of the proto-Sun crossed the barrier of 7 million Kelvins, and hydrogen nuclei, which till now were bouncing off each other, started fusing into Helium. 8. Science, v. 300, p . The standard model for the formation of the Solar System (including the Earth) is the solar nebula hypothesis. Tap again to see term . But planet formation appears to have happened relatively rapidly. The processes that followed gave rise to the solar system, complete with eight planets, 181 moons, and countless asteroids. The solar system is about 4.6 billion years old. 2.There are two types of planets. Initially the cloud was about several light years across. Jim will tell you about how the elements of the periodic table were formed. Origin of the Solar System Our theory must explain the data 1.Large bodies in the Solar System have orderly motions. . A cloud of interstellar gas, dust, and ices containing several generations of material collapsed to form the nebula from which the Sun and the rest of our solar system grew. When this dust cloud collapsed, it formed a solar nebula - a spinning, swirling disk of material. timeline for the formation of our solar system. Make sure you fully understand what causes the solar nebula to go from one step to the next. Once these clumps formed, they grew rapidly by sticking to other clumps. What were some early ideas about the formation of our solar system? The 0.1% of matter that remained orbited around the Sun, causing the randomly shaped gas cloud to form a flat disc shape. Make sure you fully understand what causes the solar nebula to go from one step to the next. Answer (1 of 15): Our current understanding is that Jupiter formed first, beginning its accretion shortly after the Sun formed. A cloud of interstellar gas and/or dust (the "solar nebula") is disturbed and collapses under its own gravity. The Sun formed in the center, and the planets formed in a thin disk orbiting around it. Over the next 600 million years, called by geologists the Hadean Era, the sun and the planets were formed, and Earth's oceans were probably created by cometary impacts. They did this by determining the age of stony materials from the asteroid belt. Solar system formed about 4.6 billion year ago, when gravity pulled together low-density cloud of interstellar gas and dust (called a nebula) (movie) . This activity involves making a simple model to give students an overview of the distances between the orbits of the planets and other . Around 5 billion years ago, an interstellar cloud of dust and gases began to collapse on itself as the force of gravity pulled the particles together. 6. This effect is known as conservation of angular momentum. What was left was gas, ice, and rocky material, which orbited around the sun because of its strong gravitational. 4)Heat from the sun . […] 1)started as swirling could of gas and dust called a Nebula 2)Gravity pulled most the matter towards the center and the cloud spun faster. Planet Formation The formation of the sun consumed more than 99 percent of the matter in the nebula. The Orion Nebula, an interstellar cloud in which star systems and possibly planets are forming. In the first module of Origins Jim Connelly and Henning Haack go through the evolution that resulted in the Solar System with the planets that we know today. Introduction For decades the solar system was assumed to be the prototype for planetary system formation. Location. Title: The Origin of the Solar System Author: Markus Boettcher Last modified by: Windows User Created Date: . Often called stellar nurseries, nebulae are the birthplace of stars. 2. Our solar system began as a collapsing cloud of gas and dust over 4.6 billion years ago. Our solar system formed about 4.6 billion years ago. The Sun sent out energy and particles in a steady stream, called stellar winds. This pulled all the gas towards the center. This unit reveals detailed facts about our Sun and the planets. And the orbits of Kuiper Belt Objects—tiny worlds far from the Sun—reveal that our planetary system had a terrifically violent past, when giant planets changed . The planets in our solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Comets are very rich in water ice. Within the solar nebula, the dust particles in the gas occasionally collided and clumped together. by University of Oxford. References: Zinner, Ernst (2003) An isotopic view of the early solar system. Order the images from a planet's beginning until it is fully formed, based on your knowledge and intuition. In this model, the Solar System formed from a large, rotating cloud of interstellar dust and gas called the solar nebula.It was composed of hydrogen and helium created shortly after the Big Bang 13.8 Ga (billion years ago) and heavier elements ejected by supernovae. As the nebula collapsed under its own gravity, it spun faster and flattened into a disk. the asteroid belt between Mars and Jupiter (thought to be failed version of planet formation). This flat disc, called the protoplanetary disc, was where the planets formed. We call such a cloud a "nebula" and more than one of them we refer to as "nebulae." There are nebulae all around our galaxy, and it's from these nebulae that stars and planets form. Planetary system formation coincides with the process of star formation in which our Sun belongs to the generation of stars created 4.6 billion years ago, when our galaxy was roughly half its present age. Planetesimals continue to collide with protoplanets, melting them. They are encouraged to use the words from the crossword in their descriptions. It provides a huge opportunity for hands-on learning activities and science experiments. With the . This first step hastened the critical process of forming the first small clumps of matter. Solar Nebula 2. Question: 6. 3)Fusion starts... a star is born. The gravity of the nebula pulls this matter into the centre, and the nebula experiences a gravitational collapse. The formation of our solar system is thought to be typical of other star systems in the universe. Existence of smaller bodies • Asteroids and comets 4.
