A planet's gravity is cause by it's mass (how big it is and it's density). The bigger it is the stronger it's gravitationally pull is. Imagine this: that all the planets are marbles (with the size of the marble equal to how big the actual planet is) and imagine that all the marbles are on a stretchy cloth suspended in air on earth, the bigger marbles should make the cloth go down in that area and causes the other marbles to come to it.
the gravitational pull of the gravity of the planet so in other words bigger planets more gravity, smaller planet less gravity. usually bigger planets have more moons
Big
Planets have gravity because they have mass.
The other planets do have gravity.
Yes. All planets have gravity. Earth is one of those inner planets.
No. Planets have gravity as a result of their own mass.
The premise of this question is incorrect; all planets have gravity.
the planets were formed by gravity because starts had gravity around them witch caused them to become bigger and be planets i think.. idk
Yes they are the sun has gravity that holds the planets in place.
All planets have gravity.
The gravity that keeps the planets in orbit is the sun's gravity, which is a product of the sun's mass.
All mass produces a gravity field. All planets have mass. Therefore all planets have gravity.
