all objects in this universe are attracted towards each other and we call that force of attraction gravity. just imagine there are two balls in your hands, one big and other one small. the big ball is earth while the small one is moon. now join both with a piece of thread such that the two balls can be separated from each other only by cutting the thread. now come out of your imaginative world and accept that in real life also the moon and earth are joined to each other not by apiece of thread but by centripetal force if this force is removed both earth and moon will fly off in a line tangent to their circular path. now i hope you have understood this concept.
Gravity provides a centripetal force on the Moon, helping it stay in orbit around Earth. TRUE!!! -iRLANDA♥
The Sun's gravity causes a planet to move in its orbit. The Sun's gravity provides a centripetal force. The effects of the Sun's gravity, combined with the planet's inertia (tendency to move in a straight line), results in a planet's elliptical orbit.
The mutual gravitational force between the satellite and the 'central' body.
The centripetal force is equal to the gravitational force when a particular body is in a circle. For a body that is in an orbit, the gravitational force is equivalent to the centripetal force.
the mutual forces of gravitational attraction between the planet and the sun
Electrostatic force of attraction between the positively charged nucleus and electron provides the necessary centripetal force in an atom.

During the revolve two forces acts on it that it centripetal force and centrifugal force. when planet approaches near the star due to centrifugal force and get attracted due to centripetal force.As both forces act simultaneously .Hence planet revolve
by means of the gravitational forces between it and the planet
The string
The forces of attraction between the sun and each planet are gravitational forces, and they're both centripetal forces.

1. Whirling of a stone tied to a string: The string provides necessary centripetal force for the rotation of stone.2. Turning of vehicles in a circular track: The friction due to the tyres in case of levelled road and the angle of inclination of tracks in case of banked tracks provides the necessary centripetal force.
