# Orbital Constants

A satellite of mass $$m$$ is orbiting a planet of mass $$M$$ at a distance $$R$$ of the planet's centroid. If $$\Gamma$$ is the Potential Energy of the satellite, and its Kinetic Energy can be written as $$\alpha \Gamma$$, $$\alpha$$ a real constant, then the correct value of $${ \alpha }^{ -2 }$$ is:

$$Details$$: Consider that the satellite's dimensions are suffiently small and that the planet is sufficiently spherical, homogeneous and distant from the satellite. Assume that $$G$$ as the Gravitational Constant
