- The Kuiper belt is a region of the solar system beyond the planets, extending from the orbit of Neptune. It consists mainly of small bodies or remnants from the solar system’s formation.
- It is similar to the asteroid belt, although it is far larger 20 times as wide, and 200 times as massive.
- The Kuiper belt objects (KBO) are composed largely of frozen volatiles (termed ‘ices’), such as methane, ammonia, and water.
- The Kuiper belt is home to at least three dwarf planets Pluto, Haumea, and Makemake.
- Pluto, discovered in 1930, is considered its largest member.
