The force of universal gravitation and momentum.
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.
Well, they are being attracted to the sun, but orbit fast enough that they don't fall into the Sun.
The Sun's strong gravity keeps all the planets in orbit around it.
The two forces that work together to keep the planets in orbit around the sun are gravity and inertia.
The gravitational force between the sun and each object in the solar system
It was Isaac Newton who figured out that the force of gravity keeps planets in orbit around the sun.
Gravity.
The suns huge gravitational force keeps the planets in an orbit around it.
the suns gravity keeps the planets in orbit

Gravity is the force that holds a planet in orbit around the sun. Inertia keeps the planets spinning.
Centripetal Force.That force is, of course, supplied by gravitional force.
