The sun is at one focus of an ellipse The farther away the foci are from each other, the more eccentric the ellipse. WebAn ellipse is defined as the locus of all points in the plane for which the sum of the distances r1 and r2 to two fixed points F1 and F2 (called the foci) separated by a distance 2c, is a given constant 2a. Therefore, from this definition the equation of the ellipse is: r1 + r2 = 2a, where a = semi-major axis. [>>>]
