एक ग्रह के चारों ओर वृत्तीय कक्षा में घूमन

The period of a satellite is given by

$T=\frac{\text { circumference of orbit }}{\text { or bital velocity }}$

$T=\frac{2 \pi r}{\sqrt{\frac{r M}{r}}}=2 \pi \times \sqrt{\frac{r^{3}}{G M}}$

where, $M$ is the mass of the planet, $r$ is the radius of the orbit and $G$ is the gravitational constant.

Thus, the period of a satellite in a circular orbit around a planet depends on the radius of the orbit and the mass of the planet about which it is revolving. Thus, it is independent of the mass of the satellite.
