Problem: The moon travels an elliptical path with Earth as one focus. The maximum distance from the moon to Earth is 405,500 km and the minimum distance is 363,300 km.
(1) What is the eccentricity of the orbit?
(2) For a planet or satellite in an elliptical orbit around a focus of the ellipse, perigee (P) is defined to be its closest distance to the focus and apogee (A) is defined to be its greatest distance from the focus. Show that is equal to the eccentricity of the orbit.
(3) Find the Apogee. Find the Perigee.

Answer by vleith(2983) (Show Source): You can put this solution on YOUR website!
Look at this --> http://www.1728.com/ellipse.htm
Then understand that perigee means 'closest point' and apogee means 'most distant point'.
You are told that the perigee is 363000. Apogee is 405500. Earth is one focus.
Let's assume that earth is f[1]
By looking at the link above, you can see that perigee is the distance from f[1] to A. Apogee is the distance from f[1] to B.
The eccentricity is the ratio of the
