You are the science officer on a visit to a distant solarsystem. Prior to landing on a planet you measure its diameter to be17000 km and its rotation period to be 22.8 hours. You havepreviously determined that the planet orbits 240000000 km from itsstar with a period of 500 Earth days. Once on the surface you findthat the free-fall acceleration is 11.8 m/s22. What is the mass ofthe planet? What is the mass of the star?
