Orbital Period For Circular Orbits Calculator

Property to Calculate:

Orbital Period (T):

Orbital radius (r):

Mass of the central body (M):

How This Is Calculated

$$ T = 2 \pi \sqrt{\frac{r^3}{GM}} $$ where:

T = Orbital period (s)

r = Orbital radius (m)

G = Gravitational constant (6.674 x 10-11 m3 kg-1 s-2)

M = Mass of the central body (kg)

Assumptions

The objects are treated as point masses.
The central body is assumed to be spherically symmetric.
There are no external forces.
The object remains in a constant circular orbit.
The gravitational field is uniform.
