Homework Statement

Consider the Earth following its nearly circular orbit (dashed curve) about the sun. The Earth has mass 5.98 *10^24 kg and the sun has mass 1.99 *10^30 kg. They are separated, center to center, by r=93 million miles=150 million km. What is the size of the gravitational force acting on the Earth due to the sun?
Homework Equations
F = G(mE)(mS)/r^2
The Attempt at a Solution
Pretty much I just plugged and chugged to try to get the answer, which of course of was incorrect.
F = (6.67*10^-11)(5.98*10^24)(1.99*10^30)/ (1.5*10^11)^2 = 3.53*10^66
