'Centripetal' means centre seeking i.e.the object tries to go towards the centre of the circle because of this force.foe example:
5 rupee coin kept on a rotating disk flies off the disk along the tangent to the disk.Thus,a force acts on the object moving along a circle and it is directed towards the centre of the circle.This is centripetal force.Planet requires to revolve around the sun is centripetal force. Sun must be attracting the planets,including the earth,towards itself. you can also explain it by kepler's law

Answer:
The centripetal force required by a planet to remain in orbit around sun is provided by gravitational force of attraction. The centripetal force depends on radius, mass and orbital speed of planet.
