In 1951 astronomer Gerard suggested Ciobr Gerard Kuiper comets regular animate the short Alguetrh must and that came from the area or place beyond Neptune, and suggested that there is rubble and the remains of the solar system is still there.This idea was enhanced awareness of scientists that must be Seen separate group of comets (called the indefinite family buyer) this group behave around different from those comets that come from long distances very cloud Oort Oort, as it revolves around the sun in a period of less than twenty years (compared to 200 million years to the Oort cloud), and because of that Mdarathm located near the Earth's orbit around the sun, and in addition to that all these comets revolve around the sun in the same direction as the rest of the planets of the solar system.And confirmed the hypothesis Ciobr in the early eighties when he used a computer in the business simulation form the solar system, according to these simulations, there is a disk of debris can form naturally around the edge of the solar system, according to this scenario, the planets clump rapidly in the interior region of the ocean starburst of the sun, and debris remaining will just gather influence the attractiveness of the sun, and thus the region beyond Neptune (last gas giants) must be the debris field of scattered objects and frigid that have not healed for the formation of planets.
With belt Ciobr theory theoretically correct without the presence of physical evidence supported until 1992 when it was revealed body diameter 240 km (named 1992QB1) in the belt questionable, followed by the discovery of several bodies similar magnitudes to confirm the existence of this belt, and quickly became a theoretical real true.
This the belt Ciobr is a region in space in the form of a disk located after Neptune's orbit and about 50 astronomical units, and contain thousands of small icy objects, which is considered a source of short period comets.The belt important Ciobr for the study of the solar system where it was possible the bodies belt Ciobr are very primitive remnants of the early stages of the formation of the solar system, is also believed widely that the source of short period comets, and is considered a store of such objects.
Some scientists believe that Triton and Pluto with its moon Charon are just examples of the objects of this belt, and was the first body of the belt Ciobr discovered in 1992.
According to the studies are expected and there are more than one hundred thousand body in this belt exceed Fifty kilometers in diameter in addition to billions of comets orbiting there, scientists estimated the mass of the belt ten times the mass of Earth. The belt consists of internal part about 50 astronomical units and a second part external distributed Ogesamh 100 astronomical units.
