Question

Calculate the average distance from the surface of the Earth at the equator of a satellite in “geostationary orbit” (i.e., whose period of revolution is equal to the period of rotation of the Earth).

Answer 1

Express the results in kilometers. 

Use Newton’s form of Kepler’s third law:

Height of satellite above the surface (h) 

h = 42,257 - 6378 = 35,879 km
