"This surprising lack of small KBOs changes our view of the Kuiper Belt
and shows that either its formation or evolution, or both, were somewhat different than those of the asteroid belt between Mars and Jupiter," said Singer.
In the last few decades, astronomers have identified three regions that exist beyond Neptune: the Kuiper Belt
, the Scattered Disc, and the Oort Cloud.
The observations were part of a survey of 50 Kuiper belt
It backs the growing belief that Pluto itself is a Kuiper belt

After a 13-year journey, the piano-sized spacecraft has covered a distance of four billion miles to reach Ultima Thule in the Kuiper Belt

As to the Kuiper Belt

First past the post on all five starts (Flat and jumps) since joining Elliott, Kuiper Belt
was relegated to second place at Listowel after beating Gold Seal by a short head in the Liam Healy Memorial Lartigue Memorial Hurdle.
Like our solar system's Kuiper Belt
, the Proxima belt contains fine grains with similar average temperature and total mass.
Comet 67P spent billions of years in the Kuiper belt
beyond Neptune, where a rain of charged particles could have created oxygen.
The known Solar System can be divided into three parts: the rocky planets like Earth, which are close to the Sun; the gas giant planets, which are further out; and the frozen objects of the Kuiper belt
, which lie just beyond Neptune's orbit.
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.
