Is the centripetal acceleration of Mars in its orbit around the Sun larger or smaller than the centripetal acceleration of the Earth?

Answer 1

On the average it is smaller, in the ratio #1/2.32#, nearly.

The centripetal acceleration is inversely proportional to the square of the distance in the solar system because every orbiter of the star Sun has the same mass.

The proportion for Mars in comparison with the Earth is (ratio of the inverse-squares of the average distances from the Sun) =#(1.496^2/2.279^2)#= 0.431, nearly

To calculate the much smaller centripetal force, multiply this ratio by the mass ratio (0.642/5i97). Almost 1/21.6, or 0.0463, is the result.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
