The object is called a meteor because it is producing a streak of light and has not yet struck Earth.

A meteor is a small body of matter from outer space that enters the earths atmosphere and appears as a streak of light.

A meteor becomes a meteorite when it strikes Earths surface. Because is has not yet struck Earths surface, it is still a meteor.

A meteor was once a meteoroid moving through space, but became a meteor once it entered Earths atmosphere.

i'd say that the moon rock is about 2.2 billion years old.
