Kearney's Comet has a radius of 262.0km and obits the solar system (goes around the sun) in a circular path. The mass of the comet is 7.98x10^15kg and its distance of 8.95x10^12m from the sun. How long does it take for the comet to orbit once around the Sun?

The answer is 463years but I could not figure out how to reach this answer.:confused:
