+"""
+The time period of a satellite is the time taken by a satellite to
+complete one full orbit around a celestial body.
+
+T = 2π * sqrt((R + h)^3 / (G * M))
+
+G is the Universal Gravitational Constant and equals 6.674 X 10^-11 N m²/kg²
+M is the mass of the celestial body (kg)
+R is the radius of the celestial body (m)
+h is the height of the satellite above the surface (m)
