Parabolic Orbit Radius

Parabolic Orbit Radius

It is closely related to the orbital velocity of a body in a circular orbit of the radius equal to the radial position of orbiting body on the parabolic

 is the radial distance of the orbiting body from the mass center of the central body,

is the specific angular momentum of the orbiting body,

 is the true anomaly of the orbiting body,

 is the standard gravitational parameter.
