meteorite
A naturally occurring solid object from interplanetary space that survives impact on a planetary surface. While in space, the object is called a meteoroid, and a meteor if it produces light or other visual effects as it passes through a planetary atmosphere. Various sounds, including hissing and thunderous detonations, have also been reported for large meteors arriving at Earth. Explosive surface impacts by large meteorites are believed to have created the plethora of craters on the solid planets and moons of the solar system. Meteor Crater, Arizona, is Earth's most famous example of an impact crater.
