Find out what the difference is between a Meteor Vs. Meteorite.  They are two different rocks, and understanding will help you better research your space rocks.

The easy explanation is that meteorites are rocks that have landed on earth.  Meteors are space rocks that are still floating around in space.  To be more technical meteoroids are in space, and meteors are just outside of the earth's atmosphere, but not quite out far enough to be a noid.

So a space rock can be all three: First it starts out as a meteoroid, floating around aimlessly in space.  Our meteoroid is small, smaller than the asteroid; it's big brother.

Our meteoroid is floating around, but then it goes off course and starts heading for earth.  It's heating up and hits the atmosphere.  It just turned into a meteor.  As it keeps going, it's large enough that it doesn't burn away upon entry to earth, and crash lands into the desert of Arizona.

It is now a meteorite.  Hurry up young hunter, and go get it!
