Formulae for free orbits

Orbits are conic sections, so the formula for the distance of a body for a given angle corresponds to the formula for that curve in polar coordinates, which is:

μ {\displaystyle \mu } is called the gravitational parameter. m 1 {\displaystyle m_{1}} and m 2 {\displaystyle m_{2}} are the masses of objects 1 and 2, and h {\displaystyle h} is the specific angular momentum of object 2 with respect to object 1. The parameter θ {\displaystyle \theta } is known as the true anomaly, p {\displaystyle p} is the semi-latus rectum, while e {\displaystyle e} is the orbital eccentricity, all obtainable from the various forms of the six independent orbital elements.
