SOLAR SYSTEM

Detailed explanation-1: -Each of these types has many sub-groups. Stony MeteoritesStony meteorites are made up of minerals that contain silicates-material made of silicon and oxygen. They also contain some metal-nickel and iron.

Detailed explanation-2: -An asteroid’s composition is mainly determined by how close it is to the sun. The asteroids that are nearest the sun are mostly made of carbon, with smaller amounts of nitrogen, hydrogen and oxygen, while the ones further away are made up of silicate rock.

Detailed explanation-3: -Meteorites and the asteroids they come from are mostly silicates. The tiny grains composing interplanetary dust particles (IDPs) are mostly silicates. Comets have been called dirty snowballs–the dirt is silicate.

Detailed explanation-4: -When meteoroids enter Earth’s atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it’s called a meteorite.
