Two newly discovered planets follow circular orbits around a star in a distant part of the galaxy. The orbital speeds of the pla
nets are determined to be 45.6 km/s and 55.1 km/s. The slower planet's orbital period is 8.68 years. (a) What is the mass of the star? (b) What is the orbital period of the faster planet, in years?
