SOLAR SYSTEM

Detailed explanation-1: -Meteoroids are lumps of rock or iron that orbit the sun, just as planets, asteroids, and comets do. Meteoroids, especially the tiny particles called micrometeoroids, are extremely common throughout the solar system.

Detailed explanation-2: -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. Watch as a meteorite travels to Earth, causes an explosion, and creates an impact crater. Video by QA International, National Geographic.

Detailed explanation-3: -There are two main types of stony meteorite: chondrites (some of the oldest materials in the solar system) and achondrites (including meteorites from asteroids, Mars and the Moon). Both chondrites and achondrites have many subgroups based on their compositions, structures and the minerals they contain.

Detailed explanation-4: -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-5: -Meteorites are fragments of rock or metal that fall to Earth from space. They are very rare, but many people find unusual rocks or pieces of metal and wonder if they might have found a meteorite.
