[quote]What do you do?[/quote]Absolutely nothing.[quote][url=http://en.wikipedia.org/wiki/Meteor#Meteor]A meteor or "shooting star" is the visible streak of light from a meteoroid or micrometeoroid, heated and glowing from entering the Earth's atmosphere, as it sheds glowing material in its wake. Meteors typically occur in the mesosphere at altitudes between 76 km to 100 km (46–62 miles).[18] The root word meteor comes from the Greek meteōros, meaning "suspended in the air". Millions of meteors occur in the Earth's atmosphere daily. Most meteoroids that cause meteors are about the size of a pebble.[/url][/quote]Learn to Astronomy.
