It keeps them in orbit.
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.
The premise of this question is incorrect; all planets have gravity.
No. Planets have gravity as a result of their own mass.
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 to some degree due to their mass. Gravity is what keeps objects, including planets, in orbit around the sun.
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.
All planets have gravity.
Gravity is the force that keeps the planets in their orbits around the sun. It pulls the planets towards the sun, while their forward motion keeps them from falling into it. Gravity also influences the shape and stability of the planets' orbits.
