Definition

1. Noun:
   • A solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon. The term specifically refers to the object after it has landed. It can be composed of stone, iron, or a mixture of both.

Examples of Usage

• Noun:
  • Scientists analyzed the composition of the meteorite.
