The orbital period is the time a satellite, moon or spacecraft takes to complete one lap around a central body, and it follows directly from the mass it orbits and the size of the orbit. Newton form of Kepler third law says the period equals two pi times the square root of the orbit radius cubed divided by the gravitational constant times the central mass. This calculator takes the central mass in kilograms and the orbit radius in kilometers, then returns the period in seconds, minutes and hours along with the circular orbital speed. It is handy for low Earth orbit satellites, geostationary planning or moons of other planets. All calculation is done locally in your browser with no server involved.
