Question

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 × 107 m and its rotation period to be 22.3 hours. You have previously determined that the planet orbits from its star with a period of 402 earth days. Once on the surface you find that the acceleration due to gravity is 59.7 m/s2. What are the mass of (a) the planet and (b) the star? (G=6.67x10^-11N*m^2/kg^2)

Group of answer choices

(a) 1.3 kg × 1026 kg, (b) 1.7 kg × 1030 kg

(a) 1.3 kg × 1026 kg, (b) 2.9 kg × 1030 kg

(a) 7.2 kg × 1025 kg, (b) 1.7 kg × 1030 kg

(a) 7.2 kg × 1025 kg, (b) 2.9 kg × 1030 kg
