SOLAR SYSTEM

Detailed explanation-1: -In simplest terms, a meteorite is a rock that falls to Earth from space. Meteorites are rocks, but they are not like Earth rocks. Most are far older, and they provide some of the only samples we have of other worlds – other planets, asteroids and possibly comets – in our solar system.

Detailed explanation-2: -Before the small bit of comet or asteroid enters Earth’s atmosphere, it floats through interplanetary space and is called a meteoroid. Most meteoroids that enter the atmosphere burn up completely as meteors.

Detailed explanation-3: -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.
