Homework Help: Physics

Posted by Thomas on Tuesday, April 22, 2008 at 3:39pm.

I have to find the eccentricity of an elliptical orbit with one focus, earth's center, E. I know the formula to find eccentricity is sqrt(1-)(b^2/a^2), but I don't know where to use the radius or if I need it. Do I just need to use the eccentricity formula to find it?
