How do shooting stars work?

A shooting star is a meteor moving fast enough through the air to create heat and light of its own. But if space is a vacuum, what air is there for it to cause the friction to create heat and light?How do shooting stars work?
A meteoroid only becomes a meteor (shooting star) once it has entered Earth's atmosphere. Meteoroids are just dust or pebbles in space before then, moving fast relative to the Earth. The friction/compression from their motion through the atmosphere usually obliterates them. If one of them does not burn up completely, but rather impacts the ground, then it is a meteorite.How do shooting stars work?
Its entering the Earths atmosphere! It doesnt burn in space!
