The gravitational constant G is less accurate than the product of G and masses for Earth and Moon. Consequently, it is conventional to express the lunar mass M multiplied by the gravitational constant G. The lunar GM = 4902.8001 km 3 /s 2 from GRAIL analyses. [12] [11] [19] The mass of the Moon is M = 7.3458 × 10 22 kg and the mean density is ...
The Lunar Traverse Gravimeter was a lunar science experiment, deployed by astronauts on the lunar surface in 1972 as part of Apollo 17.The goal of the experiment was to use relative gravity measurements to infer potential attributes about the geological substrata near the Apollo 17 landing site.
Big Muley is a 11.7 kg (26 lb) [3] breccia, consisting mainly of shocked anorthosite attached to a fragment of troctolitic "melt rock". The rock's cosmic ray exposure age was discovered to be about 1.8 million years, linking it to ejecta, or debris, from the impact that formed South Ray crater, to the south of the Apollo 16 landing site.
Descent stage may have hit the Moon, ascent stage in heliocentric orbit. Snoopy is the only flown LM ascent stage known to have survived intact (possibly asteroid 2018 AV2 [52]). LM-5 Eagle: Apollo 11: July 16, 1969 Descent stage on lunar surface in Sea of Tranquility, ascent stage left in lunar orbit (could be still orbiting the moon [53]) LM ...
The gravitational field near the Moon is weaker because the Moon has less active gravitational mass. Passive gravitational mass is a measure of the strength of an object's interaction with a gravitational field. Passive gravitational mass is determined by dividing an object's weight by its free-fall acceleration.

The standard gravitational parameter μ of a celestial body is the product of the gravitational constant G and the mass M of that body. For two bodies, the parameter may be expressed as G(m 1 + m 2), or as GM when one body is much larger than the other: = (+).
The weight of the bowling ball on the Moon would be one-sixth of that on the Earth, although its mass remains unchanged. Consequently, whenever the physics of recoil kinetics (mass, velocity, inertia, inelastic and elastic collisions ) dominate and the influence of gravity is a negligible factor, the behavior of objects remains consistent even ...
