Planetary science: A younger Moon

Alan Brandon1

Top

The most recent study of lunar rocks indicates that the Moon formed later than previously thought — a conclusion that requires our view of the early history of the inner Solar System to be revised.

It was almost 40 years ago that we found out what the Moon is made of: lunar samples collected during the Apollo missions turned out to consist of rocky material similar in composition to that found on Earth. We also think we know that the Moon formed from the accretion of molten and vaporized ejecta produced by a collision between proto-Earth and a giant Mars-sized impactor1, 2.
