The planetMars requires 2.35 years to orbit
the sun, which has a mass of 2 × 1030 kg, in
an almost circular trajectory.
Find the radius of the orbit of Mars as it
circles the sun. The gravitational constant is
6.672 × 10−11 N · m2/kg2 .
Answer in units of m
change period fromyears to seconds, look up G, solve for r
