Yes, approximately.
The moon exerts a gravitational force approximately one sixth of the gravity of earth.
The mass will remain the same, but the weight will be one sixth of what it was on earth, since weight depends on the local force of gravity. The moons gravity is one sixth of the earths.
About 0.183g, where one g is the earths gravity, so about one fifth of the earths gravity. It is similar to our own moons surface gravity.
The moon has one-sixth of the Earths gravity.
The moon's gravity is one-sixth that of the Earth's;
Of the planets in our solar system, Mars has the lowest surface gravity of around 38% of earths - over one third. This comes closest to the 25%. We then have moons and dwarf planets, but these have much lower surface gravities.
One moon, no rings.
The surface gravity on Io is very low compared to Earth, due to its low mass, around 0.183g or 18.3% of the Earths pull at the surface. this is just a little more than the surface gravity on our own moon, which is about 16.5% of earths pull.
The moon has one-sixth the gravity of earth.
As good as. If you weigh 100 lbs on earth, you would weigh 16.54 lbs on the moon. One sixth of 100 equals 16.6666.... Close enough.
The diameter of the Moon is about 1/4 (one fourth) the diameter of the Earth (more precisely 27.2%). Moon diameter = 3476 km (equator) 3472 km (polar) Earth's diameter = 12756 km (equator), 12742 km (polar)
The strength of gravity on the surface of a planet is related to the mass of the planet, the more mass, the higher the gravity. So the smallest planet, Mercury, is the planet with the lowest gravity, 0.38 of one g or 38% of Earths gravity. There are then the dwarf Planets which are smaller and have lower gravity. Ceres is one, in the asteroid belt between Mars and Jupiter, its gravity is only 0.028g, or 2.8 of Earths. Planetary moons may smaller still, having less gravity again due to their lower mass. There are some very small moons which are only a few km across - these will have a gravity (everything with mass has a gravitational field), but this will be tiny for such a small object.
