Chapter 05, Problem 39

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 44.0 km/s and 60.5 km/s. The slower planet's orbital period is 8.61 years. (a) What is the mass of the star? (b) What is the orbital period of the faster planet, in years?
