Etymology
Origin of meteor
First recorded in 1570–80; from New Latin meteōrum, from Greek metéōron “meteor, a thing in the air,” noun use of neuter of metéōros “raised in the air,” equivalent to met- met- + eōr- (variant stem of aeírein “to raise”) + -os adjective suffix
Explanation
A meteor is a space rock that hits Earth's atmosphere. It's also another word for a shooting star — which is not a star at all, but a streak of light visible in the sky when a meteor burns up in the atmosphere. There are a lot of large objects in space: stars, planets, and moons. There are smaller bodies, too, such as meteoroids — small chunks of rock or metal orbiting the sun. When a meteoroid enters Earth's atmosphere, it becomes a meteor. This word is also used for the streak of light caused when this happens, commonly called a shooting star. Sometimes there are meteor showers, when Earth passes through a trail of space objects that then burn up due to friction with Earth's atmosphere.
