Part 1. Survey of the solar system. 1. What do you know (or think you know)?. Confer with your tablemate (or people in front or back of you) and write down five things you think you know about our solar system. . The outer planets are called Jovian or Jupiter-like.. These planets are made of gas and are several times more massive than the Earth.. The Jovian planets grew to present size in about 10 million years.. http://www.cs.wright.edu/~tkprasad. Prasad. 1.

Terrestrial Planets- Mercury, Venus, Earth and Mars- relatively small and rocky . Jovian Planets- Jupiter, Saturn, Uranus, and Neptune- are huge gas giants. Session 4 – The Nebular Theory. In the past few sessions we looked at the Big Bang theory and how it tries to explain the universe as a whole. Today we will look on a smaller scale of our solar system, and how the Big Bang theory explains (or doesn’t explain) the formation of the solar system. 25.5. Any theory about the origin of the solar system must explain. why all of the planets’ orbits lie more or less in a plane . Why all of the planets orbit the sun in the same direction. . It must also explain the differences in size and composition between the terrestrial planets and the gas giants.. The processes by which stars and planets form are active areas of research in modern astrophysics. The formation of our own solar system is central to the first half of our course, and important to the second half as well when we study the formation of stars. 4.1 . The Search for Origins. Goals:. Where did the solar system come from?. How did it form?. When did it form?. What properties of our solar system must a formation theory explain? . Patterns of motion of the large bodies . Learn planetary characteristics such as number of moons, size, composition, type of atmosphere, gravity, temperature and surface features.. Understand the movement of planetary bodies..

Planets. The bodies we see in the sky from earth are called heavenly bodies or celestial bodies. They include the stars, planets, comets and the moons.. Stars. : Stars are huge balls of very hot gaseous matter. They are self-luminous celestial bodies that emit heat and light. The sun is the star nearest to the Earth..
