The orbital period is the time taken for a given object to make one complete orbit around another object. It is applicable in astronomy.
The orbital period T (in seconds) of two bodies orbiting each other in a circular or elliptic orbit is given as,
Where,
μ = G × M
G is the gravitational constant,
M is the mass of the more massive body.
a = the orbit’s semi-major axis in meters
μ = the standard gravitational parameter in m3/s2
