SPACE — The Kuiper Belt is a cold donut-shaped region of icy objects surrounding the outer solar system beyond the orbit of the planet Neptune. The Kuiper Belt is similar to the main asteroid belt, located between Mars and Jupiter, in terms of its objects.
According to the American Space Agency (NASA), the Kuiper belt consists of material left over from the formation of the solar system about 4.6 billion years ago. The Kuiper Belt is much larger than the main asteroid belt, up to 20 times wider and 20 to 100 times more massive.
Like the main asteroid belt, the Kuiper Belt is formed by the orbits of the giant planets. If the gas giant Jupiter forms the structure of the main asteroid belt, then the orbit of the cloudy Neptune forms the structure of the Kuiper belt. Neptune’s orbit prevented matter from merging into a large planet and thus carved out the thin disk of the Kuiper Belt.
The following are facts about the Kuiper Belt:
1. Just Explored
Humans have only just begun to explore the Kuiper Belt with two spacecraft that have already traveled there.
2. In 1983, the Kuiper Belt region was visited by NASA’s Pioneer 10 spacecraft, which crossed the belt but did not visit any of its planets.
Furthermore, the New Horizons space probe carried out investigations on Pluto and Charon in 2015. Pluto and Charon are objects in the Kuiper Belt. The spacecraft then visited other Kuiper Belt objects including Arrokoth.
3. The Kuiper Belt is a collection of small, ice-filled objects that orbit the sun farther than Neptune. The Kuiper Belt is very similar to the asteroid belt, but cooler and farther from the sun.
4. According to NASA, the Kuiper Belt is truly a frontier in space. The Kuiper Belt is a place that is only just beginning to be explored. Understanding of the Kuiper Belt is still evolving.
5. Types of objects found in the Kuiper Belt
The icy objects in the Kuiper Belt are called “Kuiper Belt Objects” or KBOs for short. Pluto is the most famous KBO. Only Pluto and one other KBO, Arrokoth, have been photographed up close by spacecraft.
All other KBOs have only been studied using telescopes. Even the best telescopes on Earth and in orbit still see these objects as dots because they are so far away.
6. What makes Kuiper Belt objects interesting?
There are thousands of objects that we know of of various sizes. These objects are waiting to be discovered and measured by astronomers. Every single one of these objects is a bit of leftover planetary material that formed somewhere in the solar system and was placed in its current orbit.
7. NASA says that the doughnut-shaped inner edge of the Kuiper Belt begins at the orbit of Neptune and is about 4.8 billion kilometers from the sun.
8. The interior of the Kuiper Belt is 30 Astronomical Units away and the edge of the main region is about 50 AU. 1 Astronomical Unit is the distance between the Earth and the Sun.
9. There is another, more irregular region of the Kuiper belt called the “discarded disc” that continues outward to about 1,000 AU from the sun. These distances indicate that the Kuiper Belt is one of the largest structures in the solar system.
