The Mars meteorite NWA 7533 is 4.4 billion years old and contains evidence of long-ago asteroid strikes, suggesting that the rock came from the Red Planet's ancient and cratered southern highlands, researchers saidSomebody up there playing pool? Must be a black hole nearby.

Can someone with some understanding of this field explain, how do we know that this is a piece of Mars? Thank you!
