| 6. How are asteroids and comets different? |
| 7. Draw a comet, and label the nucleus, coma, ion, and dust tails. Why are there two tails? |
| 8. What are typical densities for comets and asteroids? What does this tell us about what they are made of? |

| 15. Where are most meteorites on Earth found? |
| 16. Where did the material that asteroids and meteorites are made of come from? |
