Inertia is the force that causes planets to move in a straight line. The gravity of a more massive body, such as the sun, causes them to fall into orbit instead of continuing in a straight line.
The gravitational force from the Sun keeps planets in orbit around it. Additionally, the forward motion of the planets balances the pull of gravity, preventing them from falling into the Sun.
Isaac Newton concluded that the force of gravity and the forward motion of the planets combined to keep them in orbit around the Sun. The force of gravity pulls the planets towards the Sun, while the forward motion of the planets creates the centrifugal force that counteracts gravity, leading to stable 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.
The planets continue on their orbits due to a balance between the gravitational force pulling them toward the sun and their velocity providing the necessary centripetal force to keep them in motion. This balance creates a stable orbit as the planets move around the sun.
The gravitational force produced by the sun keeps the planets in orbit around it. This force pulls the planets toward the sun, creating a continuous circular motion rather than a straight line out into space.

The gravitational force between planets supplies the centripetal force that causes them to orbit each other.

Newton's laws of motion state that an object at rest remains at rest and an object in motion remains in motion unless acted upon by a force. Since planets are constantly moving in their orbits, the fact that they do not travel in a straight line but follow a curved path implies that a force, such as gravity, must be acting on them to keep them in orbit around the Sun.
According to the Newton's first law of motion,each body continues it's motion until a force is exerted.In the outer space there might be no force in the opposite direction which is capable to make the planets stationery even after the BIG BANG THEORY.
A force is not required to keep an object in motion, according to Newton's First Law of Motion. An object in motion will continue moving at a constant velocity unless acted upon by an external force that causes a change in its motion.

Gravity is considered to be the major force in the universe, governing the motion of planets, stars, and galaxies.
The planets continue on their orbits due to a balance between the gravitational force pulling them toward the sun and their velocity providing the necessary centripetal force to keep them in motion. This balance creates a stable orbit as the planets move around the sun.
