SOLAR SYSTEM

Detailed explanation-1: -The Kuiper Belt is a doughnut-shaped ring of icy objects around the Sun, extending just beyond the orbit of Neptune from about 30 to 55 AU.

Detailed explanation-2: -This distant region is probably populated with hundreds of thousands of icy bodies larger than 100 km (62 miles) across and an estimated trillion or more comets. Dwarf planet Pluto may be the best known of the larger objects in the Kuiper Belt.

Detailed explanation-3: -How many planets are in the Kuiper Belt? Due to Neptune’s gravitational influence, there are no planets in the Kuiper Belt. However, the belt contains four of the five officially recognized dwarf planets: Pluto, Eris, Makemake, and Haumea.

Detailed explanation-4: -The Oort Cloud is a spherical layer of icy objects surrounding our Sun, a star, and likely occupies space at a distance between about 2, 000 and 100, 000 astronomical units (AU) from the Sun.

Detailed explanation-5: -Asteroids, comets and Kuiper belt are bodies smaller than planets that orbit the sun. Asteroids are composed of metals and rock, whereas comets also contain ice and dust. The Kuiper belt is a collection of such bodies that orbits at the edge of the solar system.
