A question from Gravitation.

Prince Patel Asked:
“Sun have high gravitational energy ,then why planets of solar system doesn’t colloid with sun?”
Answer:

“The planets are moving around the sun and the gravitational force is used in providing the necessary centripetal force (The force required by a body to move in a circular path). As long as the planets are in motion, they will not move towards the sun. A similar explanation hold good for moon going around earth also.”
