Define the periodic time (orbital period) of a satellite.

(N/A) The periodic time $(T)$ of a satellite is defined as the total time taken by the satellite to complete one full revolution around the central body (such as a planet or star) in its orbit.
Mathematically,for a satellite at a distance $(r)$ from the center of a planet of mass $(M)$,the orbital period is given by:
$T = 2\pi \sqrt{\frac{r^3}{GM}}$
where:
$G$ is the universal gravitational constant,
$M$ is the mass of the central body,
$r$ is the orbital radius (distance from the center of the planet to the satellite).
