Where do meteors come from, what are they made up of and how often do they come down?
Meteors are small pieces of rocks or metals.You can always see it as a shooting star on a clear moonless night.They are formed due to the breakage of comets,when they pass very close to the sun.So they come from the outer space ,enter our atmosphere and most of them get completely burnt in the atmosphere due to friction.The larger meteors may survive the heat produced by friction and may not be completely burnt.These blazing objects which manage to reach the earth are called meteorites. Thus a meteor is a relatively small body that has become incandescent because of the heat of friction in passing through the earth’s atmosphere.When the earth’s orbit crosses the orbit of the comet,these meteors fall on the surface of the earth as a shower.
