This activity explores models for the elliptical orbit of Jupiter. Problem 1 reviews the geometric definition of an ellipse as students calculate for a and b from the perihelion and aphelion of Jupiter and then graph the ellipse. Problem 2 develops the concept of a parametric curve by using a data capture to discover the coordinate equations of an ellipse.
