Earth vs Mars vs Moon gravity at elevation Radial gravity anomaly at the surface of the Moon in mGal. 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]

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.
The New Shepard mission is far from the first to carry scientific payloads to the edge of space, but it was the first to mimic the moon's gravity.. The gravitational pull of the lunar surface is ...
With a diameter of about 5,270 kilometres (3,270 mi) and a mass of 1.48 × 10 20 tonnes (1.48 × 10 23 kg; 3.26 × 10 23 lb), Ganymede is the largest and most massive moon in the Solar System. [45] It is slightly more massive than the second most massive moon, Saturn's satellite Titan, and is more than
When the moon’s orbit brings it closer to Earth than usual, the cosmic combo is called a supermoon. Here's how to see it in the night skies.
An illustration of light sources from magnitude 1 to 3.5, in 0.5 increments. In astronomy, magnitude is a measure of the brightness of an object, usually in a defined passband. An imprecise but systematic determination of the magnitude of objects was introduced in ancient times by Hipparchus. Magnitude values do not have a unit.
