The acceleration due to gravity on the surface of the Moon is approximately 1.625 m/s 2, about 16.6% that on Earth's surface or 0.166 ɡ. [1] Over the entire surface, the variation in gravitational acceleration is about 0.0253 m/s 2 (1.6% of the acceleration due to gravity).
On average the Moon's surface gravity is 1.62 m/s 2 [4] (0.1654 g; 5.318 ft/s 2), about half of the surface gravity of Mars and about a sixth of Earth's. The Moon's gravitational field is not uniform. The details of the gravitational field have been measured through tracking the Doppler shift of radio signals emitted by orbiting spacecraft.
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 ...
Soil studied by India’s Chandrayaan-3 mission near the lunar south pole adds support to the theory that the moon once had a magma ocean billions of years ago. ... surface, located within 164 ...
Io (/ ˈ aɪ. oʊ /), or Jupiter I, is the innermost and second-smallest of the four Galilean moons of the planet Jupiter.Slightly larger than Earth's moon, Io is the fourth-largest moon in the Solar System, has the highest density of any moon, the strongest surface gravity of any moon, and the lowest amount of water by atomic ratio of any known astronomical object in the Solar System.
The surface gravity, g, of an astronomical object is the gravitational acceleration experienced at its surface at the equator, including the effects of rotation. The surface gravity may be thought of as the acceleration due to gravity experienced by a hypothetical test particle which is very close to the object's surface and which, in order not to disturb the system, has negligible mass.
Still, the spacecraft has already accomplished a historic feat, becoming the first commercial spacecraft to soft-land on the moon, and the first US-made vehicle to touch down on the lunar surface ...
Gravity passes through matter. In addition to surface mass, a high-resolution gravity field gives a blurred, but useful, look below the surface. Analyses of the GRAIL data have produced a series of scientific results for the Moon. The resolution of the gravity field has improved by a large amount over pre-GRAIL results.
