Detailed explanation-1: -Meteoroids are small rock pieces that revolve around the Sun. They are usually made up of dust, ice particles and gases. Some meteoroids enter the Earth’s atmosphere with a great velocity. Most comets have a head, a nucleus and a tail.
Detailed explanation-2: -Meteoroids are what we call “space rocks” that range in size from dust grains to small asteroids. This term only applies when they’re in space. Most are pieces of other, larger bodies that have been broken or blasted off.
Detailed explanation-3: -In the Solar System Most meteoroids come from the asteroid belt, having been perturbed by the gravitational influences of planets, but others are particles from comets, giving rise to meteor showers. Some meteoroids are fragments from bodies such as Mars or the Moon, that have been thrown into space by an impact.
