It is similar to the asteroid belt, but is far larger--20 times as wide and 20 to 200 times as massive . Like the asteroid belt, it consists mainly of small bodies or remnants from when the Solar System formed . While many asteroids are composed primarily of rock and metal, most Kuiper belt objects are composed largely of frozen volatiles (termed "ices"), such as methane, ammonia and water . The Kuiper belt is home to three officially recognized dwarf planets: Pluto, Haumea and Makemake . Some of the Solar System's moons, such as Neptune's Triton and Saturn's Phoebe, are thought to have originated in the region . </P> <P> The Kuiper belt was named after Dutch - American astronomer Gerard Kuiper, though he did not predict its existence . In 1992, 1992 QB was discovered, the first Kuiper belt object (KBO) since Pluto . Since its discovery, the number of known KBOs has increased to over a thousand and more than 100,000 KBOs over 100 km (62 mi) in diameter are thought to exist . The Kuiper belt was initially thought to be the main repository for periodic comets, those with orbits lasting less than 200 years . Studies since the mid-1990s have shown that the belt is dynamically stable and that comets' true place of origin is the scattered disc, a dynamically active zone created by the outward motion of Neptune 4.5 billion years ago; scattered disc objects such as Eris have extremely eccentric orbits that take them as far as 100 AU from the Sun . </P>
