•Material on the moon is like our crust and mantle. Very little iron is there.•No atmosphere on the moon due to high energy impact.•Same oxygen atoms are on the earth and moon that are different from ones found in comets and meteoriods!

Collision Theory Evidence !

Comparisons:

1/4 our diameter

1/6 our gravity

About 240,000 miles away
