Ratio of Mechanical Energy to Kinetic Energy


A satellite orbiting the earth in a circular orbit has a well defined potential energy and a well-defined kinetic energy. The sum of the kinetic and potential energies is the mechanical energy of the satellite.

What is the ratio of the mechanical energy to the kinetic energy of a satellite in a circular orbit of the earth? Specifically, what is:

$$\cfrac{\text{Mechanical Energy}}{\text{Kinetic Energy}}=?$$
