1. Nebular Theory

2. How would you define/ describe the following: 1. What is the Solar System? 2. What are the Planets in our Solar system? 3. The order of the Planets? 4. What is the Sun? 5. What are Asteroids? 6. What are Meteors? 7. What are Meterorites?

3. 1. What is the Solar System? – All of the stuff that is “near” our sun- planets, moons, asteroids, etc. 2. What are the Planets in our Solar system? – MVEMJSUNP 3. The order of the Planets? 4. What is the Sun? – Big Ball of burning Gas…. 5. What are Asteroids? – “small” Rocky bodies- mostly in between the orbits of Mars and Jupiter 6. What are Meteors? – A “space rock” that falls through our atmosphere and burns up 7. What are Meterorites? – A meteor that does not burn up, and hits the ground

4. How did Our Solar System get here? Nebula: A big blob of gas and dust. It has gases that “want” to expand, but the spinning of the huge cloud keeps it intact.

5. It Begins to spin, forms a big ball shaped structure, and flattens out in the middle.

6. Gravity begins impacting the particles, causing some to become a “protosun”, and dust and other debris to become “protoplanets”.

7. After millions* of years, a solar system with planets, etc. develops
