Comet and Astroid
- Comets are big chunks of rock and ice left over from the formation of stars and planets
- Comets form when planets were
- comets formed about 4.6 billion years ago
- They are formed outer parts of the solar system
- Comets and planets both orbit the sun
- They both follow Kelper's law where the closer they get to the sun the quicker they move
- Planets orbit in more of a circular pattern around the earth while comets orbit in a vertical elliptical pattern
- Comets have tail when they are by the sun
- The ice melts due to the suns heat it produces a tail of water vapor, gas, and dust
- When a comets is visible from earth it looks like a rock
- Comets that are seen through through telescopes look like shooting stars
