Circular orbital period
The period of a circular orbit follows directly from gravity and circular motion.
Formula usedT = 2π√(r³/GM)
Visual cue · circular motion

Example 2
A geostationary-radius orbit gives a period close to one sidereal day.
Good to knowThe relation assumes a circular orbit and a dominant central mass.
