Detailed explanation-1: -About 100, 000 comets more than 100 km across. Kuiper belt comets orbit the Sun in the same direction (CCW) as the planets. Kuiper belt comets lie close to the plane of planetary objects.
Detailed explanation-2: -Astronomers have now linked the comet’s appearances to observations dating back more than 2, 000 years. Halley was last seen in Earth’s skies in 1986 and was met in space by an international fleet of spacecraft. It will return in 2061 on its regular 76-year journey around the Sun.
Detailed explanation-3: -Scientists believe that comets are made up of material left over from when the Sun and the planets were formed. They think that about 100, 000 million comets orbit the Sun. Some comets orbit the Sun like planets. Their orbits take them very close to and very far away from the Sun.
Detailed explanation-4: -The correct statement about comets is: C. Comets are mostly made up of dust particles, frozen water and frozen gases.
Detailed explanation-5: -Comets are huge ice and dust particles that revolve around the Sun in an orbit. Thus, comets are part of our solar system.
