Kuiper Belt Objects

In 1930, the University of Chicago astronomer, Fredrick Leonard postulated that beyond the orbit of Neptune, there would be debris left over from the formation of the major planets. He called this debris, "plantesimals", rubble that had never manage to stick together to form larger bodies.
In 1951, the Dutch-American space researcher Gerard Kuiper wrote briefly about the region beyond Neptune, but dismissed the possibilty that there might be a large population of small objects, or, "minor planets" there.
In the mid-1990s it became widely recognized by professional astronomers of the existence of plantesimals by the observations of the Irish amateur astronomer, Kenneth Edgeworth. Due to this, the term for the region of minor planets at the edge of the solar system is now strictly termed as the "Edgeworth-Kuiper Belt". Because of possible claims of discovery, this region is now often referred to as "trans-Neptunan Objects" (TNOs).
The Kuiper Belt is a ring of icy asteroids that begins near to the orbit of Neptune and finishes near the orbit of Pluto.
The objects in the belt are almost certainly a sampling of material preserved from the formative years of our Solar System, when the planets were accumulating mass and growing into the objects we see today.
In 1992, two astronomers, Dave Jewitt and Jane Luu, both of Hawaii's Institute for Astronomy, found a distant object circling the Sun beyond the orbit of Neptune. It was later designated "1992 QB1". Other discoveries followed in rapid succession with nearly twenty discovered in the next two years.
Today there are over 1000 known Kuiper Belt Objects (KBO's), it is believed there are around 40,000 objects larger than 100km across.
Stretching from 30AU to 48AU (1AU or "Astronomical Unit" is equal to the distance between the Earth and Sun. 150,000,000km)
KBO's orbit near the ecliptic, forming a band like the asteroid belt but much bigger.
