The increase in orbital radius actually decreases the average orbital speed. This is a scientifically proven fact. The increase in orbital radius by 50 percent will decrease the average orbital speed by approximately 18 percent. On the other hand, the decrease in orbital radius will increase the average orbital speed.

Answer:

Inverse relationship between orbital radius and orbital speed

Explanation:

Orbital speed is defined as the average speed or the instantaneous speed at a specific point in its orbit. The mathematical expression for the orbital speed is given by :

[tex]v_o=\sqrt{\dfrac{GM}{r}}[/tex]......(1)

Where

G is the universal gravitational constant

M is the greater mass body and a smaller mass body orbits around it.

r is the orbital radius.

So, form equation (1) the average orbital speed is inversely proportional to the average orbital speed. On increasing orbital radius, average orbital speed decreases.
