Moon rocks on Earth come from four sources: those collected by six United States Apollo program crewed lunar landings from 1969 to 1972; those collected by three Soviet uncrewed Luna probes in the 1970s; those collected by the Chinese Lunar Exploration Program's uncrewed probes; and rocks that were ejected naturally from the lunar surface before falling to Earth as lunar meteorites.
The Apollo 11 mission to the surface of the Moon returned a few dozen pounds/kilos of lunar material (mainly rock and dust), and the US put about 0.05 grams in small display cases and gave one apiece to the 50 U.S. states, to the nations of the world, and to political entities like the U.S. territories under administration.

The oldest Moon rocks are up to 4.5 billion years old, [37] making them 200 million years older than the oldest Earth rocks, which are from the Hadean eon and dated 3.8 to 4.3 billion years ago. The rocks returned by Apollo are very close in composition to the samples returned by the independent Soviet Luna programme.

It was found in the Fra Mauro region of the Moon. Big Bertha is the first discovered meteorite from Earth, and the embedded meteorite portion is the oldest known Earth rock. At 8.998 kg (19.84 lb), this breccia rock is the third largest Moon sample returned during the Apollo program, behind Big Muley and Great Scott.
The moon may be older than some scientists thought, according to a new study. It suggests that rock samples from the Apollo missions date back to a melting event, not to the moon's formation.
The Genesis Rock (sample 15415) is a sample of Moon rock retrieved by Apollo 15 astronauts James Irwin and David Scott in 1971 during the second lunar EVA, at Spur crater on Earth's Moon. With a mass of c. 270 grams (4,200 grains), [1] it is currently stored at the Lunar Sample Laboratory Facility in Houston, Texas.
