ab: Summary: 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.
