The orbit of a planet is an ellipse where one focus of the ellipse is the sun. An ellipse is defined by two focii and all points for which the sum of the distances are the same. The semimajor axis (a) is the long distance from the center to edge of the ellipse. If r 1 and r 2 are the distances from the focii to any point on the ellipse then r 1 + r 2 = 2a.The short axis is called the semiminor.
