9. The Sun When you click on the sun you will hear from Tim and Moby. They will spew dozens of fun facts about our very own star (yes, the sun is really a star), the sun! You’ll find out about its huge size as well as just how hot it is, both on the surface and in the sun’s middle parts (let’s just say you’d fry if you got anywhere near it)! You’ll also discover what the sun’s made of, as well as how it got its start way back at the beginning of our solar system’s history. And, you can find out what neat things go on near the sun’s surface, while getting pointers about how to protect yourself from the sun’s powerful rays. This movie is “solarly” cool, man!

10. Our solar system contains: – The sun – 9 Planets (or 8 if you take away Pluto). – All the planets revolve around the sun – The sun uses gravitational force (pull) on each planet to keep all of the planets in orbit around it. – The planets all exert gravitational force (pull) on their moons and any spacecraft that come near them. – A bigger planet exerts a greater gravitational force than a smaller planet.

11. Let’s Hear From Tim and Moby Again! Click on the picture of the space shuttle to hear what Tim and Moby have to tell us about our Solar System and the Planets.

13. 1. Mercury 2. Venus 3. Earth 4. Mars They are the four planets closest to the sun.

14. Inner Planets: They all have rocky surfaces, and they are warmer than the outer planets.

15. Earth is different from the other inner planets. It has a watery surface. It is the only planet with a lot of oxygen in its atmosphere. Earth has plant life and animal life.

16. 1. Jupiter 2. Saturn 3. Uranus 4. Neptune

17. Outer Planets are made mostly of frozen gases. Their surfaces are colder than the inner planets because they are farther away from the sun. Most outer planets have many moons.

18. Pluto: Is It really a planet??? Some scientists now believe that Pluto is really just a moon that once belonged to Neptune. Anyway, it is now called a dwarf planet.

19. Compare the Planets’ Sizes

20. Here is a song you may hear when you meet Solar Max. They come from space No they don’t come from here These are the Spase Peepole They are from A different Planet Spase Peepole They’re not of this Earth They’re from outer space Ohhh, Spase Peepole Spase Peepole I was outside one day in my backyard And I saw the Spase Peepole Camped out in my yard They said We are not from here We’re Spase Peepole We’re not of this Earth Cause we are from space Ohhh Spase Peepole Spase Peepole!
