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' m and its rotation period to be 22.3 hours. You have previously determined that the planet orbits 6.8 x 1011 m from its star with a period of 402 earth days. Once on the surface you find that the acceleration due to gravity is 66.3 m/s-. What are the mass of (a) the planet and (b) the star? (G = 6.67 x 10-11 N . m2/kg2) O (a) 8.0 x 1025 kg, (b) 1.5 x 1032 kg O (a) 1.5 x 1026 kg, (b) 1.5 x 1032 kg O (a) 1.5 x 1026 kg, (b) 9.1 x 1031 kg O (a) 8.0 x 1025 kg, (b) 9.1 x 1031 kg
