This idea proposes that there were a lot of small bodies left over after the formation of the inner planets, enough to make abo ...

Lunar Roving Vehicle
The Lunar Roving Vehicle (LRV) or lunar rover was a battery-powered four-wheeled rover used on the Moon in the last three missions of the American Apollo program (15, 16, and 17) during 1971 and 1972. It was popularly known as the moon buggy, a play on the phrase ""dune buggy"".The LRV was transported to the Moon on the Apollo Lunar Module (LM) and, once unpacked on the surface, could carry one or two astronauts, their equipment, and lunar samples. The three LRVs remain on the Moon.
