Meteors

A meteor is a very small meteoroid that has entered the earth's atmosphere. Such objects have speeds approaching 70 kilometres per second.Also called shooting star the bright streak of light appearing in the sky is due to the friction when the meteoroid enters the atmosphere and turns into a meteor.

A meteorite is the remaining of a meteor that did not burn up from friction.

A meteoroid is a space rock that's bigger than dust grain but smaller than a asteroid. That is when the meteoroid is in space.
