Chapter 12, Problem 42EAP
Comet Tails. Describe in your own words why comets have tails. Why do most comets have two distinct visible tails, and wThy do the tails go in different directions) Why is the third, invisible tail of small pebbles of interest to us on Earth?

Describe the relationship between meteor showers and comets.
Why do meteor showers occur about on the same day each year?
Originally thought to be the realm of comets, over the past two decades we discovered that the Kuiper Belt region hosts also many other objects similar in size to Pluto (Figure 22).
This seems to imply that there are two completely different types of objects in the region.
Do you think that both types of objects formed in this region, or some of these may have migrated to this region at a later time? Briefly explain your reasoning.
O e. as a moon
QUESTION 3
You observe a large, round object orbiting Uranus. How would you classify this object?
O a. as a planet
Ob. as a dwarf planet
Oc. as an asteroid
Od. as a Kuiper belt object
e. as a moon
QUESTION 4
What is one difference between asteroids and Kuipter Belt Objects (KBOS)?
O a. asteroids are composed of rock and ice, while KBOS are composed of just rock
b. asteroids orbit the Sun, while KBOS orbit Pluto
C. asteroids orbit between Mars and Jupiter, while KBO's orbit near Pluto
d. asteroids have very elliptical orbits, while KBOS have very circular orbits
e. asteroids are small and potato-shaped, while KBOS are large and round
