SOLAR SYSTEM

Detailed explanation-1: -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. Some come from comets, others from asteroids, and some even come from the Moon and other planets.

Detailed explanation-2: -Comets are frozen leftovers from the formation of the solar system composed of dust, rock, and ices. They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet.

Detailed explanation-3: -Meteorites. A meteorite is a fragment of spatial matter that falls to the surface of a planet. Most meteorites that fall to Earth come from the Asteroid Belt.

Detailed explanation-4: -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-5: -Meteors are called meteoroids before they reach Earth’s atmosphere. Meteoroids are smaller than asteroids and range from the size of boulders down to the size of tiny sand grains. Still smaller objects are called interplanetary dust.
