meteor
Definition
A meteor is a piece of rock or metal that enters Earth's atmosphere from space. When a meteor enters Earth's atmosphere, it heats up and glows. This is called a shooting star.
Most meteors burn up completely in the atmosphere and never reach the ground. However, if a meteor is large enough, it can survive the trip through the atmosphere and land on the ground. This is called a meteorite.
Meteorites can be very small or very large. The largest meteorite ever found on Earth is the Hoba meteorite, which weighs over 60 tons!
Meteorites are very valuable to scientists. They can learn a lot about the formation of the solar system by studying meteorites.

The literal meaning of the word "meteor" is "something that rises up in the air". This is because meteors are small bodies of rock or metal that enter Earth's atmosphere from space and vaporise due to friction.
