It's not made of cheese
CAPE CANAVERAL, FLORIDA- New research adds strength to the theory that the moon was created by a collision between earth and a planet-sized object about four and a half billion years ago.
Scientists from Germany studied moon rocks gathered from astronauts in the Apollo 11, 12 and 16 missions and found the rocks have a different makeup than rocks on Earth.
The results also suggest the moon is made up of a 50-50 mixture of the object and Earth.
The findings fit the notion that the moon would contain material from the object that struck earth.
