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

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.
