The region of the solar system between Mars and Jupiter contains many asteroids that orbit the Sun. Consider an asteroid in a circular orbit of radius 5.8 1011 m. Find the period of the orbit.

Steve,
the period T of an asteroid at distance R from the sun, is given by
T^{2}/R^{3} = 4pi^{2}/GM
where G is the gravitational constant and M is the mass of the sun
fill in the numbers and solve for T.

John,
T^2/R^3=4pi^2/GM >T^2/5.8e11=4pi^2/(6.673e11)(1.99e30) is this how it's supposed to be setup?
