Two newly discovered planets follow circular orbits around a star in a distant part of the galaxy. The orbital speeds of the planets are determined to be 38.1 km/s and 54.8 km/s. The slower planet's orbital period is 8.16 years.
(a) What is the mass of the star?
(b) What is the orbital period of the faster planet, in years?
