Prior to landing on a planet you measure its diameter to be 1.80 x 107 m and its rotation period to be 22.3 hours. You have previously determined that the planet orbits 2.20 x 10 m from its star with a period of 402 earth days. Once on the surface you find that the free-fall acceleration is 12.2 m/s. What is the mass of the planet? Express your answer with the appropriate units. View Available Hint(s) mp = Value Submit Request Answer Units ?
