C. the gravitational pull of the Sun
What is centripetal force?
The force which is necessary to keep an object moving in a curved path and that is directed inward toward the center of rotation a string on the end of which a stone is whirled about exerts centripetal force on the stone compare centrifugal force.
Here,
Gravitational attraction provides the centripetal force needed to keep planets in orbit around the Sun and all types of satellite in orbit around the Earth.
The Earth's gravity keeps the Moon orbiting us.
Gravity supplies the necessary centripetal force to hold a satellite in orbit about the earth.
The gravitational attraction of the Sun is an inward (centripetal) force acting on Earth. This force produces the centripetal acceleration of the orbital motion.
Therefore , The centripetal force needed to keep Earth in orbit by the gravitational pull of the Sun.
The complete question is:
What provides the centripetal force needed to keep Earth in orbit?
A. inertia
