Part A 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 1.5 x 101 m from its star with a period of 402 earth days. Once on the surface you find that the acceleration due to gravity is 11.8 m/s2. What are the mass of (a) the planet and (b) the star? (G = 6.67 x 1071 N m-/kg-) (a) 26 x 1025 kg. (b) 9.8 x 10- kg O (3) 14 x 1025 kg. (b) 1.7 x 10 kg (a) 26 x 102 kg. (b) 17 x 1030 kg O (a) 14 x 1025 kg. (0) 98 x 102 kg Submit Request
