The moon's gravity is one-sixth that of the Earth's;
The moon's gravity is about 1/6th of Earth's.
Your would weigh 1/6th as much as you do here on mother Earth. The how is our moons' mass, and therefore its' gravity, is about 1/6 as much as the Earths'. Its' gravity well is not as deep as the Earths.
Mars' moons are much smaller than, for example, Earth's Moon, or the larger moons of Jupiter. A large moon will have a larger gravity, which will tend to pull the moon together into a spherical shape.
Earths surface of gravity is 4.6m/s2 more than moons.
Planet Mercury and Planet Earth are both rocky planets. But Mercury is much smaller than Earth, so has much less force of gravity. Your answer is "No".
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.
Yes, both Ganymede and Callisto, which are moons of Jupiter, have gravity due to their mass. However, the gravitational force on these moons is weaker than on Earth because they are much smaller and less massive.
No, the Sun does not have Earth's gravity; rather, it has its own gravitational pull, which is much stronger due to its larger mass. The Sun's gravity is what keeps the Earth and other planets in orbit around it. Earth's gravity, on the other hand, is what keeps objects on its surface and influences the orbits of its moons and artificial satellites.
the moon has less gravity... because the moon is smaller and and its gravitational pull is MUCH lower than the earths
Weaker, much weaker.
Approximately 109 Earths could fit across the sun's diameter, based on the sun being about 109 times wider than Earth. Since the moon is much smaller than Earth, it would take many more moons than Earths to fill the circumference of the sun.
Smaller. Much smaller.
