Centripetal Force.
That force is, of course, supplied by gravitional force.
It was Isaac Newton who figured out that the force of gravity keeps planets in orbit around the sun.
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.
Planets are kept in elliptical orbits due to the gravitational force acting between the planet and the sun. This force causes the planet to move in a curved path, resulting in an elliptical orbit. The balance between the planet's inertia and the gravitational force determines the shape of the orbit.
The force of gravity between the moon and the planet is what keeps the moon in orbit around the planet. This gravitational force prevents the moon from floating away into space and keeps it in a stable orbit.
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 suns gravity keeps the planets in orbit

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.

Planets in our solar system are kept in orbit by the gravitational pull of the sun. The balance between the centrifugal force of the planet's movement and the gravitational force of the sun keeps them in a stable orbit.
The suns huge gravitational force keeps the planets in an orbit around it.
the gravititonal pull does; it is what keeps all the planet in the suns orbit xx
Gravity is the force that keeps us grounded on Earth and planets in orbit around the sun. Gravity is a pulling force that attracts objects with mass towards each other. In the case of planets orbiting the sun, the gravitational force from the sun keeps them in their respective orbits.
The question probably means "What keeps the planets in orbit around the Sun?" The answer to that is : The Sun's gravitational attraction provides the force needed to keep the planets in orbit. This force doesn't pull the planets any closer to the Sun, but it stops the planets moving away (at a tangent to their orbits) due to their own velocities.
