You are the science officer on a visit to a distant solar system. Prior to landing on a planet you measure its diameter to be 1.8 x 10^(7) m and its rotation period to be 22.3hours . You have previously determined that the planet orbits 2.2 x 10^(11) m from its star with a period of 387 earth days. Once on the surface you find that the free-fall acceleration is 12.2 m/s^(2).
What is the mass of the planet?
What is the mass of the star?
