\n" ); document.write( "According to Kepler's third law of planetary motion, the average radius R of the orbit of a planet around the sun is determined R=T^2/3, where T is the number of years for one orbit and R is measured in astronomical units.
\n" ); document.write( "a. It takes Mars 1,881 years to make one orbit of the sun. What is the average radius in AUs of the orbit of Mars?
\n" ); document.write( "b.The average radius of the orbit of Saturn is 9.05 AU. How many number of years does it take for Saturn to make one orbit of the sun?
