How does acceleration of mars around the sun compared to the acceleration of the Earth?

Hint :Acceleration, property of the motion of a body traversing a circular path. The acceleration is directed radially toward the center of the circle and features a magnitude adequate to the square of the body's speed along the curve divided by the space from the center of the circle to the moving body.

Complete Step By Step Answer:
There is no such thing as force or acceleration for objects in orbit. Einstein's general theory of relativity states that gravity isn't a force but a distortion of space time. The Sun's mass distorts the 4 dimensional fabric of space time.
All of the planets follow geodesics, which are the space time equivalent of straight lines within the space time which has been distorted by the Sun. The concepts of gravity and force come from Newton's theories.
Centripetal force only applies to spinning objects like a weight on the top of a string. Einstein said that gravity and acceleration are indistinguishable to an observer. Nevertheless, gravity and force keeping an object in orbit don't exist.

Note :
Any net force causing uniform circular motion is called a force. The direction of a force is toward the middle of curvature, an equivalent because the direction of acceleration. Consistent with Newton's second law of motion, net force is mass times acceleration: net F = ma.
