1. Planet X belongs to the planetary system of a distant star. The radius of Planet X was determined through direct observation by the exploration ship to be Rx = 7.22X103 km. An exploration team sent to the surface measured the gravitational acceleration to be gx = 10.6 m/s2.

(a) Use the information given about Planet X to find its mass, Mx. (Explain every step)

(b) The exploration ship orbits Planet X at an altitude of 1.70X10^3 km. What is the orbital period of the exploration ship? (Explaon every step)
