-- On line or in a book, look up the acceleration due to gravity on the Earth.
-- On line or in a book, look up the acceleration due to gravity on the Moon.
-- Divide the Moon's number by the Earth's number. The answer is the fraction
of Earth's gravity that you'll encounter on the moon.
-- You can do the same for every planet in the solar system, plus several moons
and asteroids.
An object on the Moon's surface weighs 16.55% as much as the same object weighs when it's on the Earth's surface. The fraction is roughly 1/6.

Everything has gravity, the bigger it is the more it has. Moons DO have gravity, but it might be less than Earth's.
The moon's gravity is essentially identical to 100% of the moon's gravity, and results in gravitational forces on its surface that average about 16% of the corresponding forces on the Earth's surface.
by gravity
Mercury has no moons, Venus has no moons, that is 2 Earth Mars, Jupiter, Saturn, Uranus and Neptune all have moons, that is 6 Therefore the fraction of planets with out moons in the solar system is 1/3
gravity
There is gravity. There is gravity on all planets, moons, and stars.
Our moons gravity.
Gravity keeps them in orbit around Jupiter.
Yes, approximately.
because their gravity is so strong that the moons are pulled in.
