Discovery and Location

The Kuiper Belt, sometimes referred to as the Edgeworth-Kuiper Belt, is a circumsolar disk in the outer Solar System, extending from the orbit of Neptune at approximately 30 astronomical units (AU) out to about 50 AU from the Sun. It is similar to the asteroid belt but is much larger—20 times wider and 20 to 200 times more massive. Like the asteroid belt, it primarily consists of small bodies, but unlike the asteroid belt's rocky and metallic composition, Kuiper Belt Objects (KBOs) are primarily composed of frozen volatiles, often referred to as "ices," such as methane, ammonia, and water.

Merging black holes and neutron stars have unusual oval orbits prior to colliding and merging, which challenge the laws of physics.
