Activities for Students: Ellipses and Orbits: An Exploration of Eccentricity

Rose Sinicrope and Daniel V. Bellittiere 

October 2011, Volume 105, Issue 3, Page 220

Abstract:
The orbits of planets about the sun and satellites about the earth are elliptical. The shape of the orbit can be described by its eccentricity and can be modeled algebraically and graphically. The exploration of orbits enriches our understanding of the mathematical representations, definitions, and connections for ellipses.
