Question

From Where the planets get energy to rotate itself and revolve around sun?

Answer 1

Planets do not require additional energy to revolve around the sun.  Unlike objects inside earth's atmosphere there is no friction or opposing force trying to stop planets from orbiting the sun.  Planets have found that equilibrium between their own momentum and the gravitational pull from the sun to follow nearly perfect orbits.  

Answer 2

!. the turning core

2. Gravity

Answer 3

From the formation of the solar system. There is no resistance to planetary rotation, nothing to slow them down, so they just keep spinning, and no resistance to their orbits around the sun, so they keep on orbiting also.

Answer 4

This comes from grvitational pull and angular momentum.

Answer 5

Gravity keeps the planets in orbit, and inertia keeps them rotating.  They are already moving, and it would take energy to stop them, not to keep them going - Newton's laws, a body in motion stays in motion unless acted upon.

Answer 6

The angular momentum involved in each case (revolution and rotation) is the sum of that of the bit and pieces that assembled to form each planet. Since there is essentially no friction, the original energy suffices to keep the planets in their orbits, and rotating on their axes according to Kepler's laws.

Answer 7

Energy?

Gravity causes the planets to revolve around the sun  

Answer 8

gravity, newton second's law of physics..  

Answer 9

It comes from the gravitational pull of the sun
