The Kuiper Belt is named for Dutch astronomer Gerard Kuiper (1905–1973) who in 1951, proposed the existence of a disc-shaped region of icy objects beyond Neptune from which comets originate.

How many dwarf planets are there in our solar system? The recent discovery of 2017 OF201 makes the tally anywhere between ...

There appears to be a gap between 55 AU and 70 AU where no objects have yet been found, and then a second belt — let's call it "Kuiper Belt 2" — between 70 and 90 AU, which is as far out as 13 ...

The Kuiper Belt is an elliptical plane in space spanning from 30 to 55 times Earth's distance from the sun, or 2.5 to 4.5 billion miles (4.5 to 7.4 billion kilometers).

Today, researchers know that the Kuiper Belt stretches from a distance of roughly 30 astronomical units from the sun — around the orbit of Neptune — to roughly 55 astronomical units.

Amazon's next group of Kuiper satellites could soon reach orbit, propelling the company closer to providing internet to customers around the world.

Their unique nature has to do with their relative distance from both the Sun and the “first” Kuiper Belt, which lies roughly 35 to 55 astronomical units (AU) out from the center of our Solar ...

The Kuiper Belt is home to Pluto and thousands of other worlds of varying size. Most of the bodies there are made from the building blocks of our solar system, long since cordoned to distant cold ...

The Kuiper belt is somewhat similar to the asteroid belt: It contains small bits of rock and ice, all leftovers from the violent process of making planets.
