Orbital Period (Kepler's Third Law) Calculator
where:
T = Orbital Period (s)
a = Length of the semi-major axis (m)
G = Gravitational Constant (6.674 x 10-11 Nm2kg-2)
M = Mass of the central body (kg)
- The objects are treated as point masses.
- The mass distribution of the objects are spherically symmertric.
- The bodies are in stable circular or eliptical orbits.
- The system is simplied to the interaction between two bodies.
