Kuiper belt

A disk of some 107 to 109 comets that hugs the plane of the planetary system and lies between about 35 and 1000 AU from the Sun. Chiron may have come from this disk.

Kuiper Belt

[′kī·pər ‚belt]
(astronomy)
A vast reservoir of icy bodies in the region of the solar system beyond the orbit of the planet Neptune, with diameters estimated in the 100-1200-kilometer (60-750-mile) range. Also known as Edgeworth-Kuiper belt.

The Kuiper Belt is a vast region of the solar system beyond Neptune's orbit.
That makes it "a milestone in Kuiper belt science and in our understanding of the outer solar system's development," says Alessandro Morbidelli of the Observatory of the Cote d'Azur in Nice, France.
Many Kuiper Belt Objects have had informal names at first, before a formal name was proposed.
Spencer added that these observations are great practice for possible close-up looks at about 20 more ancient Kuiper Belt objects that may come in the next few years, should NASA approve an extended mission.
From the amount of sky searched, Sheppard and Trujillo determine that about 900 objects with orbits like Sedna and 2012 VP113 with sizes larger than 1000 km may exist and that the total population of the inner Oort cloud is likely bigger than that of the Kuiper Belt and main asteroid belt.
Pluto, minor-planet designation 134340 Pluto, is the largest object in the Kuiper belt, and the tenth-most-massive body observed directly orbiting the Sun.
Since then, scientists have found several Kuiper belt objects (KBOs) that are nearly as big as Pluto, including one called Sedna (see "Planets on the Edge").

It is located four billion miles from Earth in a region known as the Kuiper belt where comets originate.
The telescope will have a wide variety of uses including: the search for potentially threatening earth-approaching asteroids, exploration of the outer solar system, including the newly discovered Kuiper Belt, and investigations of distant stars and galaxies.
The names follow four broad themes: pioneering space missions, historic explorers who crossed new frontiers, scientists and engineers who contributed to our knowledge of Pluto and the Kuiper Belt, and underworld mythology.
