A planet with 20 times the earth's mass and 3 times its radius exists. It orbits a star with twice the sun's mass with a circular orbit of radius 18 AU where 1 AU is the earth sun distance. 1. What is the period of the planet's orbit in years? 2. Suppose something weighs 1600 books (books is a unit of mass) on that planet, what is it weight on earth in books?
