The Kuiper Belt/Disk

Basic facts about the kuiper belt:

The Kuiper belt, often known as the bordering, or the ´final frontier´ of our solar system. The Kuiper belt, is made of KBOs (= Kuiper belt objects), which is mainly made up of icy object, orbiting the sun. Pluto is recognized as the largest object (celestial) in the kuiper belt.
Astronomers, estimate that the disk-like belt's area would be around, 12 - 15 billion kilometers, and stretches around 11 billion Km beyond Neptune's orbit (30 - 50 AU from the Sun). The kuiper belt is mainly made up of comet-like icy objects.
Scientist agree that the main KBOs are situated 30-50 AU, however, there may be some KBO that stretch out as far as 130 AU from the sun.
The amount of KBO existing is yet not positive, but scientist agree that there are aroung 70,000 KbO orbiting the sun in the kuiper belt.
