kuiper

a belt circling the planets

Pluto=king of the Kuiper belt.

the Kuiper Belt (sometimes referred to as the Kuiper-Edgeworth Belt) is an area of the outer solar system that is estimated to stretch across 20 astronomical units (AU) of space.

kuiper was named after a Greek astronomer Jerald Kuiper.

The Kuiper Belt is a disc-shaped region of icy bodies - including dwarf planets such a Pluto - and comets beyond the orbit of Neptune. It extends from about 30 to 55 AU and is probably populated with hundreds of thousands of icy bodies larger than 100 km (62 miles) across and an estimated trillion or more comets. The first Kuiper Belt Object was discovered in 1992.
