The force that keeps all of our planets in rotation is gravity.
Answer:because the sun is like a big ball of mass which means that the planets pull the mass from the sun which keeps the planets in their rotation but if there was not mass then all the planets would go on a straight line.
The force of gravity.
The gravity of there star keeps them on path and a planets moon is sun around by its planets gravitational force
The force that keeps planets in orbit is gravity. Gravity is the attractive force that exists between two masses, such as a planet and a star, that causes them to be drawn towards each other. In the case of planets orbiting a star, gravity keeps the planets in their elliptical paths around the star.

Gravity
The main force that keeps planets in orbit around the Sun is gravity. The gravitational pull from the Sun keeps the planets moving in their elliptical paths. This force of gravity is what maintains the balance needed for a planet to stay in orbit.
The gravitational force exerted by the Sun keeps all the planets in their orbits. This force balances the planets' tendency to move in a straight line and keeps them moving in elliptical orbits around the Sun.
