Answer:

Explanation:
The constant speed means that ball is not experimenting acceleration. This elements is modelled by using the following equation of equilibrium:


Now, the exerted force is:

The volume of a sphere is:



Lastly, the force is calculated:


D is the point where the planet moves the fastest. This is because it is in the perihelion, where the planet is moving at it’s fastest pace
