Two answers . No. 1 :it's the force of gravity says Newton No. 2 :there is no force. The mass of the sun curves space-time. Each planet moves along what is, for it, the easiest path says Einstein Which one is right ? Well, Newton is right to a pretty close approximation, but Einstein is even closer. The orbit of Mercury is well predicted by Einstein's theory, but not by Newton's.

The force of gravity between the sun and the planets keeps them in orbit. This force is balanced by the planets' inertia, allowing them to maintain stable orbits around the sun. If the gravitational force were weaker, the planets would escape the solar system.
The force of gravity. Any mass will have gravity, the magnitude of which depends on the size of the mass. The earth and the moon attract each other, but at the same time their speeds relative to each other work in the opposite direction. These forces are balanced out like two people spinning while holding each others hands.
There is no force that prevents things crashing into each other. The fact that they do not crash into each other does not mean there is something preventing it.
Each planet is in its own stable orbit round the Sun, with the force of gravity pulling it towards the Sun, but that force is exactly balanced by an acceleration towards the Sun according to Newton's laws of motion.
The sideways speed of the planet means that the acceleration only makes the planet continuously curve towards the Sun without ever going much closer.
The force of gravity between the planets and the sun keeps them in orbit and prevents them from flying out of the solar system. The sun's gravitational pull keeps the planets in stable orbits around it.
The force of the Sun's gravity keeps them in their orbits.
Gravity is the force that causes planets to orbit the Sun in our solar system. The gravitational pull of the Sun keeps the planets in their orbits as they travel around the central star.
The gravitational force between the sun and the planets keeps them in orbit. This force acts as a centripetal force that continually pulls the planets towards the sun, keeping them in a stable orbit. The balance between the planet's velocity and the gravitational force determines the shape and size of their orbits.
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.
