In the figure the blue planet has a period of 1 year and an average distance from the sun of 1.73 x 1011 meters. If the average distance from the sun for the red planet is 1.39 x 1011 meters, what is its period to the nearest hundredth of a year?
So I thought maybe they through in the information on the blue planet to confuse me, so disregarding that information, I used the formula:
T=(2pi/square root of GM)*r^3/2
where G=6.67e-11 and M is the mass of the sun=2.0e30kg
Unfortunately, this isn't correct, and I don't see where I am supposed to incorporate the information about the blue planet with the red planet.
