Gravity acceleration at the surface of the Moon in m/s 2. Near side on the left, far side on the right. Map from Lunar Gravity Model 2011 Archived 2013-01-14 at the Wayback Machine. The missions with accurate Doppler tracking that have been used for deriving gravity fields are in the accompanying table.
The Moon is Earth's only natural satellite, orbiting at an average distance of 384 399 km (238,854 mi; 30 Earths across).It faces Earth always with the same side.This is a result of Earth's gravitational pull having synchronized the Moon's rotation period with its orbital period (lunar month) of 29.5 Earth days.
Thermal state of the Moon at age 100 Ma. [1] Having a mean density of 3,346.4 kg/m 3, [2] the Moon is a differentiated body, being composed of a geochemically distinct crust, mantle, and planetary core. This structure is believed to have resulted from the fractional crystallization of a magma ocean shortly after its formation about 4.5 billion ...
Previously, the moon’s gravity could only be simulated for a few seconds at a time at NASA's zero-gravity research facility or for about 20 seconds during parabolic flights. Blue Origin ...
The Moon in a general sense exhibits very little seismic activity but particularly in the frequency bands suited to the study of gravitational waves, the moon exhibits a noise level orders of magnitude lower than found on Earth. [31] [32] [33] Areas on the Moon's surface that are in permanent shadow, such as at the lunar poles, are thermally ...
The study, for the record, also attempted to pinpoint exactly how far apart moon and Earth time are, as estimates have wavered between 56 and 59 microseconds per day.
Some scientists say the “Lunar Anthropocene” epoch started in 1959 when the first spacecraft sent by humanity landed on the moon. And it’s just the beginning.
This is a list of most likely gravitationally rounded objects (GRO) of the Solar System, which are objects that have a rounded, ellipsoidal shape due to their own gravity (but are not necessarily in hydrostatic equilibrium). Apart from the Sun itself, these objects qualify as planets according to common geophysical definitions of that term.
