What is the difference between a meteorite and a meteoroid?

Meteoroids are small moving debris in space that, when caught up in the gravity of a planet turn into meteor or meteorites. Meteoroids are the ones still in space. Asteroids are large debris in soace that are mainly found in an orbit, not moving around. The most known amount of asteroids near us is the Asteroid belt separating the terrestrial planets and the gas planets.
Asteroid - a small rocky body orbiting the sun. Large numbers of these, ranging in size from nearly 600 miles (1,000 km) across (Ceres) to dust particles, are found (as the asteroid belt) esp. between the orbits of Mars and Jupiter, though some have more eccentric orbits, and a few pass close to the earth or enter the atmosphere as meteors. Meteoroid - a small body moving in the solar system that would become a meteor if it entered the earth'satmosphere.
