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.

The sun exerts a gravitational force on each planet and this gravitational force is just enough to provide the centripetal force of the circular motion of the planets around the sun.
The planets orbit the sun. The sun is at the center of our solar system and exerts a gravitational pull that keeps the planets in orbit around it.
The Sun's strong gravity keeps all the planets in orbit around it.
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.
Planets orbit the sun because gravity keeps them from escaping, and momentum keeps them moving forward. The orbits are elliptical, which is like an oval.
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.
