Kuiper Belt

We present to your attention 10 interesting facts about the Kuiper belt and the Oort cloud located beyond it:

The Kuiper Belt and the Oort Cloud are regions of space inhabited by icy bodies and comets, much smaller in size than the Earth's natural satellite.

The Kuiper Belt and Oort Cloud surround the only star in our planetary system. The Kuiper Belt is a donut-shaped ring, and the Oort cloud is a spherical shell.

Long-period comets (orbital period of more than 200 years) arrive in the inner solar system from the Oort cloud, while short-period comets (orbital period less than 200 years) originate in the Kuiper belt.

Within the Kuiper belt, there can be hundreds of thousands of ice bodies over 100 km in size and about a trillion or more comets. The Oort cloud can contain over a trillion ice bodies.

Some dwarf planets within the Kuiper belt have a thin atmosphere that collapses when their orbits carry them farthest from the Sun.

Some dwarf planets within the Kuiper belt have natural satellites.

In these areas of space, not a single object has yet been found that would have rings.

New Horizons is the first and so far the only spacecraft to reach the largest object in the Kuiper belt, the dwarf planet Pluto. This event took place in July last year.

No signs of life were found in these regions of the solar system.

The Kuiper Belt and Oort Cloud are named after astronomers who predicted their existence in the middle of the last century. We are talking about Gerard Kuiper and Jan Oort.
