Hi All,
What formula can I use to find the mass of a star given the mass of a planet and its period and orbital radius?
Thanks in advance!
What formula can I use to find the mass of a star given the mass of a planet and its period and orbital radius?Newton's form of Kepler's Third Law. Here's the meter-kilogram-second version.
M = 4 pi^2 a^3 / (G P^2) - N
Where
M = the mass of the star in kilograms
N = the mass of the planet in kilograms
pi = 3.14159265358979
a = the average separation of the star and the planet, in meters
P = the period of the orbit in seconds
G = 6.67428E-11 m^3 kg^-1 sec^-2
M = (5.915E+11 kg sec^2 m^-3) a^3 / P^2 - NWhat formula can I use to find the mass of a star given the mass of a planet and its period and orbital radius?( m1 + m2 ) P2 = ( d1 + d2 ) 3 = R3
