- What is a comet?
- How do comets give clues to the original conditions of the solar
- If all of the objects in our solar system (Sun, planets, moons, etc.) formed
from the same material, why are most meteorites and comets useful for finding out

- What are the four components of a comet when it is close to the Sun

their characteristic colors?
- Which way do the tails point? Why is a comet's tail in front of a comet
as it moves away from the Sun?
- How are long period comets associated with the Oort Cloud? How is
the Oort Cloud known to exist if it has not been observed?
- What direction can long period comets come from? What causes a comet in
the Oort cloud to head toward the inner solar system?
- How are short period comets associated with the Kuiper Belt?
- What direction do most short period comets come from?
- How were the Oort Cloud and Kuiper Belt formed?
- What is the difference between a dwarf planet and a planet? Why is Pluto now considered a dwarf planet?
- How are the meteors in a meteor shower
different from the ordinary meteors you can see on any night of the year?
