Question

Mercury has the most elliptical orbit of any planet in the solar system. Mercury orbits the Sun, as depicted in the diagram. The Sun and Mercury are attracted to each other by gravitational force. Is there any torque encountered by Mercury due to the gravitational force around the center of the sun? Justify your response.

Accepted Answer

No, at all the positions the net torque acting upon Mercury is zero because the gravitational force and the moment arm vector are always in the same direction.

Answer

Yes, there is always a torque acting upon Mercury because the gravitational force and the moment arm vector are always perpendicular.
