We cannot be certain, since we've never sent a probe out that far with the proper equipment to detect anything. We _expect_ to find a vast toroidal volume (doughnut-shaped) of space with some asteroids, a few minor planets, and LOTS of left-over junk from the formation of the solar system.
the KUIPER BELT
The Kuiper Belt is named after Gerard Kuiper; he was one of the only scientists who had theories about the Kuiper belt in the early fifties
it's sometimes called the Edgeworth-Kuiper belt
The asteroid belt is sometimes referred to as the "main belt," while the Kuiper belt is also known as the "Edgeworth-Kuiper belt."
Kuiper belt
The full name of the Kuiper Belt is the Edgeworth-Kuiper Belt. It is named for the astronomers Kenneth Edgeworth and Gerard Kuiper. The Kuiper Belt is a region of the Earths solar system that is found beyond the planets. It extends from the orbit of Neptune.
No. The Kuiper belt is out past the orbit of Neptune.
The kuiper belt are a collection of rocks beyond the orbit of Pluto. All the dwarf planets (except Ceres) are near the Kuiper Belt.
Yes, it is a moon of Pluto, which is a Kuiper belt object.
No. The Kuiper belt is thirty to fifty times farther from the sun than Earth is.
astroid belt
Objects in the Kuiper Belt often have a temperature of just 50K, or -223.15 Centigrade.
