They're relatively small...something the size of a pebble, and not much larger than a baseball, usually. They start to burn upon entering the atmosphere, about 60 miles up.

The average shooting star is pretty small less than the size of a pea.
They enter the atmosphere at less than 100,000 feet at maybe 40,000 or 50,000 thousand miles per hour an are vaporized in less than a second.
The vaporization deal is not the same as E=MC2 or there would be a gigantic explosion.

I read the average shooting star is the size of a grain of sand, and it is streaking through the stratosphere about 80 miles up, at about 25,000 miles per hour.
