Gravity keeps the planets together

Gravity
Gravity, inertia, and gravitational force.
the gravity of the sun pulls them in a circular motion.
The Sun has a powerful gravitational pull. This, combined with the velocities of the planets, keeps the planets in orbit.
Actually, it's the gravity of the sun that keeps the planets in orbit around it. The force of gravity between the sun and the planets causes them to be pulled towards the sun, while their momentum keeps them moving in a circular or elliptical path.
The Sun's Gravitational pull keeps the planets orbiting it, not flying into deep space.
The Sun's strong gravity keeps all the planets in orbit around it.
The planets are kept in orbit around the sun due to the gravitational force between them. This force, which is a balance between the planet's inertia and the sun's gravitational pull, keeps the planets moving in a stable path around the sun.
Because of Gravity or Because their gravitational pull towards the other planets or sun keeps it in one place.
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 gravity of there star keeps them on path and a planets moon is sun around by its planets gravitational force
