Abstract
"The locus of points such that the sum of the distances between each point and two other fixed focii is constant." This definition of the ellipse, that figure from geometry so important to the understanding planetary and stellar orbits, may be familiar, yet it often remains confusing. We find that creating an ellipse in front of a class as we discuss its features helps to clarify this mathematical definition.
