Heredity,discovery, and IAU commision.
Some stars have been given names thousands of years ago, hence we have kept those names.
If you discover a new star, the naming of that star MAY be given to you, or named after you (i.e. Barnards Star, doscovered by E.E. Barnard)
The IAU (International Astronomical Union ) is the only group on the planet that can officially name stars. Companies may try to sell you a naming right, but the name is not 'Officially' recognized, except by that company.

Firstly, meteors are not stars, but just tiny pieces of Space debris. Many of them are pieces left behind by comets.
They enter our upper atmosphere at anything from 11 kms per second to 40 or 50 kms/sec.
Some of the ones you see after midnight enter faster because after midnight you are on the side of Earth pointing the way the Earth is travelling around the sun, so they have the added speed of the Earth's travel in its orbit (like a head-on collision).
The Earth's orbital speed is about 30 km/sec, so this vastly increases the impact speed if the meteors are not travelling in the same direction (many of them are, though).
Oops, I read that question wrong - I thought it said "falling star". Anyway, some good info here.
