The radius of the earth’s (almost circular) orbit around the sun is 150,000,000 km, and it takes 1 y for the earth to go around the sun. Imagine that a certain satellite goes in an almost circular orbit of radius 15,000 km around the earth (this radius is 10,000 times smaller than the earth’s orbital radius around the sun). What is the period of this orbit?
A. 10-6 y B. 10-4 y C. 10-3 y D. 106 y E. These periods are not related in any simple way.
