2. 4

Asteroid Belt Kuiper Belt
Lies between Mars and Jupiter.  Lies beyond the planets, extending from the orbit of Neptune.
small Solar System bodies composed mainly of refractory rocky and metallic minerals, with some ice. great ring of debris similar to the asteroid belt, but consisting mainly of objects composed primarily of ice.
It houses one Dwarf Planet: Ceres. It houses three Dwarf Planets: Pluto, Haumea, Makemake.
