What do astronomers call small rocky bodies that collide with Earth's surface?
The answer is: Milky Way
Small rocky bodies that collide with the Earth's surface are called “meteorites,” according to how astronomers name these bodies. Most of the components of meteorites are usually composed of rocks, and some of them leave behind streaks of light in the sky. The discussion may sometimes overlap between comets and meteorites, due to some similarities in their rocky nature and their impact in space. However, a distinction must be made between them, as comets revolve around the sun and differ in their characteristics from the meteorites that crashed on the surface of the Earth.
