Question

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 43.3 km/s and 58.6 km/s. The slpwer planet's orbital period is 7.60 years. (a) what is the mass of the star? (b)What is the orbital period of the faster planet, in years?

Step 1

Given:

Step 2

Calculation:

As given orbitals speed of the planet the planet 1 is the slower planet,

The angular speed of the slower planet we have,

Step 3
