Grid showing location of artificial objects on the moon (axis shows latitude and longitude)
The following table is a partial list of artificial objects on the surface of the Moon. The list does not include smaller objects such as the retroreflectors and Apollo Lunar Surface Experiment Package. Nor does it include several commemorative or personal objects left there by Apollo astronauts, such as the golf balls from Alan Shepard's lunar driving practice during Apollo 14, flags, or the Fallen Astronaut statuette left by the crew of Apollo 15.
Five third stages of rockets from the Apollo program are the heaviest pieces. While mankind has left over 170,000 kg of Earth on the Moon, only 382 kg of the Moon has been returned to Earth by Apollo and Luna missions.
The only artificial objects on the Moon that are still in use are the retroreflectors for the Lunar Laser Ranging Experiment left there by Apollo astronauts.
Note that objects listed as being at greater than 90 degrees east or west are on the far side of the moon. These include Ranger 4, Lunar Orbiter 1, Lunar Orbiter 2 and Lunar Orbiter 3.
- ^ a b c d e f g h i j k l Spacecraft was in lunar orbit but is assumed to have decayed from orbit and crashed into the moon, location unknown.
- ^ a b c d e f The ascent stage of Apollo 10 was commanded to fire its engine, left lunar orbit and entered solar orbit. The ascent stage of Apollo 11 was left in orbit and thereafter its orbit decayed and it crashed onto the moon at an unknown location. The Apollo 16 ascent stage failed to crash onto moon when commanded and it decayed from orbit at a later date and also crashed at an unknown location. The ascent stages of the remaining successful missions (Apollo 12, 14, 15, and 17) were each deliberately crashed onto the moon. Apollo 13's complete Apollo Lunar Module burned up in Earth's atmosphere after having served as a lifeboat during the aborted mission.
- ^ a b c Luna program sample return mission; mass listed is for both ascent and descent stages, though only the descent stage was left on the moon.
- ^ Lander and rover weighed 1814 kg; the rest assumed to have decayed in orbit and impacted the moon.
- ^ Was injected into lunar orbit in 1990, assumed to have decayed from orbit.
