the bigger the planet the more gravity it has because it needs to hold it self together so it has more gravity than smaller planets who require a small amount of gravity to hold themselves toghther
Gravity keeps planets in orbit around the sun. If planets were not subject to the gravitational attraction of the sun, they would fly off into interstellar space. In addition, gravity is also what holds planets together. If there were no gravity, the planets, and the sun, would disintegrate under the force of their own spin. There would be nothing left of the solar system but an expanding cloud of gas and dust.
It keeps the solar system together because without it we would be floating around. :)
i know only one and it's a good one, the sun's gravity pulls the planets from flying some where else EDIT: Gravity pulls objects together and angular momentum makes sure planets orbit
Not all of the planets are held by gravity.
Planets move away by gravity not holding it together and also gravity holds planets together
Gravity keeps the planets together

Gravity holds everything together in the galaxy. (planets)
Gravity and inertia.
The two forces that work together to keep the planets in orbit around the sun are gravity and inertia.

Gravity.
No. The outer planets do not have solid surfaces. Those planets are made of gases held together by gravity.
gassy planets are made of gas that is stuck together by gravity. Also the answer is in the question.
Gravity pulls in the sun and the planets to stay together in the orbit . The planets have gravitational force between them so they wont fall out.
