Two newly discovered planets follow circular orbits around a starin a distant part of the galaxy. The orbital speeds of the planetsare determined to be 44.3 km/s and 60.5 km/s. The slower planet'sorbital period is 7.03 years. (a) What is the mass of the star? (b) What is the orbital period of the faster planet, in years?
