My notes from Dr. Frederick D. Leonard's Meteoritics 118 class which I took
at UCLA (I believe in1962) say:

A meteorite is any object of sub-planetary mass which has landed on Earth,
or some other astronomical body, and still retains its original cosmic
characteristics.

(Little did he know that someday we would photograph meteorites residing on
the surface of Mars!)
