Yes, the word "itself" refers to the meteorite (or, more properly, the
meteoroid) and an artificial body would be a spacecraft of some sort.

OK, so some questions regarding the definition:
1) What would be considered an artificial body?
2) I am 99.9% sure that the word "itself" refers to the meteorite (as
opposed to the body on which the meteorite lands). Correct?
