caption_attribution_description: Lunar Laser Ranging Experiment with the stereo camera in the background (NASA image number AS11-40-5952). This Retroreflector was left on the Moon by astronauts on the Apollo 11 mission. Astronomers all over the world have reflected laser light off the reflectors to measure precisely the Earth-Moon distance.
context_page_description: This is a partial list of artificial materials left on the Moon, many during the missions of the Apollo program. The table below does not include lesser Apollo mission artificial objects, such as a hammer and other tools, retroreflectors, Apollo Lunar Surface Experiments Packages, or the commemorative, artistic, and personal objects left by the twelve Apollo astronauts, such as the United States flags, the commemorative plaques attached to the ladders of the six Apollo Lunar Modules, the silver astronaut pin left by Alan Bean in honor of Clifton C. Williams whom he replaced, the Bible left by David Scott, the Fallen Astronaut statuette and memorial plaque placed by the crew of Apollo 15, the Apollo 11 goodwill messages disc, or the golf balls Alan Shepard hit during an Apollo 14 moonwalk.
  Five S-IVB third stages of Saturn V rockets from the Apollo program crashed into the Moon, and are the heaviest human-made objects on the lunar surface. Humans have left over 187,400 kilograms of material on the Moon.
