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 1.8x10^7m and its rotation period to be 22.3 hours. You have previously determined that the plant orbits 2.2x10^11 m form 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^2
A) What is the mass of the planet (answer should be in kg and SHOULDN'T depend on x10)
B) What is the mass of the star (answer should be kg and SHOULDN'T depend on x10)
