The gravitational force between planets supplies the centripetal force that causes them to orbit each other.
Gravity is what sets the planets in motion. The force that keeps them in motion is known as inertia in the law of physics.
Relativity is a theory of gravity, and gravity governs the motion of planets. This is your answer in a nutshell. If you want a detailed answer, then I suggest you start studying general theory.
Planets orbit the sun in a counter clockwise motion, due to the balance between the Sun's gravity and the gravity of each individual planet.
You know that no planets actually orbit the earth right? ...?
the gravity of the sun pulls them in a circular motion.
The motion of the planets are governed by a number of factors: Gravity - The planets are being pulled towards the Sun in free fall. The velocity of the planets - This balances against the force of gravity opposing it and producing on balance the orbit. The mass of the planets. The effect of gravitational attraction between the planet and any satellites it has. The effect of gravitational attraction between the planets and other planets/dwarf planets etc.
Gravity and motion. Gravity pulls the planets in and keeps them from flying away, while the velocity of the planets keeps them from being sucked in completely.
earths rotation around the sun
Gravity keeps planets in their orbits.Newton's laws of motion and universal gravitation explain how orbits work, but have no influence whatsoeveron causing it to work that way.
Gravity draws the planets toward the sun so that they are essentially in freefall, but their sideways motion relative to the pull of gravity causes them to miss the sun by the time they would have fallen into it.
the suns gravity pull creates the earths movement as well as the other planets
