What’s the Difference Between an Asteroid and a Meteor?

The 2012 DA14 asteroid zipped passed Earth today and a meteor exploded over Russia. What the heck is the difference between an asteroid and a meteor? And a meteorite? And a meteoroid? Not too much, apparently!

An asteroid is a rocky object in space that's not as big as a planet and isn't a moon. There are millions of them, think the asteroid belt in space. A meteor is an asteroid that burns up as it enters the Earth's atmosphere, think shooting stars. A meteorite is a meteor that actually lands on the surface of Earth, think about Russia today.

As for a meteoroid? No one really knows. They're just kind of like smaller asteroids. More here.

Thanks for the guide man. A friend and I were confused because we were told that the asteroid had nothing to do with what hit Russia but it's still so confusing for me.
