![### Question 15 of 20
**Current Attempt in Progress**
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 46.3 km/s and 64.8 km/s. The slower planet’s orbital period is 7.39 years.
(a) What is the mass of the star?
(b) What is the orbital period of the faster planet, in years?
