Mass in Kepler's Third Law (given period and semimajor axis)

Formula

Mass in Kepler's Third Law (given period and semimajor axis) formula
M
mass of the primary body
P
the orbital period of planet
a
the semimajor axis of the orbit

Formula description

The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit. The third law captures the relationship between the distance of planets from the Sun, and their orbital periods. G = 6.673848E-11 N.m2/kg2.
