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).
The orbit changes over the course of the year so the distance from the Moon to Earth roughly ranges from 357,000 km to 407,000 km, giving velocities ranging from 1.100 to 0.966 km/s.
With a radius of about 1,080 miles (1,740 kilometers), the Moon is less than a third of the width of Earth. If Earth were the size of a nickel, the Moon would be about as big as a coffee bean. The Moon is an average of 238,855 miles (384,400 kilometers) away.
Yes, there is gravity on the moon. The moon has a surface gravity of around 1.62 meters per second squared, according to NASA. In comparison, the Earth has a surface gravity of...
Its surface gravity is about one sixth of Earth's, about half of that of Mars, and the second highest among all Solar System moons, after Jupiter 's moon Io. The body of the Moon is differentiated and terrestrial, with no significant hydrosphere, atmosphere, or magnetic field.
GRAIL's Gravity Map of the Moon This animation illustrates how the tilt of the Moon’s orbit often keeps it out of alignment with the Sun and Earth, preventing frequent eclipses. Why Don't We Have a Solar Eclipse Every Month?
It is a spherical rocky body, probably with a small metallic core, revolving around Earth in a slightly eccentric orbit at a mean distance of about 384,000 km (238,600 miles). Its equatorial radius is 1,738 km (1,080 miles). Because of the Moon’s small size and mass, its surface gravity is only about one-sixth of Earth’s.
The gravity on the Moon is Approximately 1.62 meters per second squared, compared to Earth’s gravity, which is about 9.81 meters per second squared. This weaker gravity affects how things move and behave on the Moon, and it’s essential to consider when planning missions or experiments there.
We know that the Moon has almost no atmosphere and only about one-sixth of Earth’s gravity. We even know that there is quite a bit of frozen water tucked away in craters near the Moon's poles. There is no wind or air on the Moon to help “erase” craters, so the surface is covered with the remains of old and new impacts.
