One of six Keplerian elements, it describes the shape of an orbit. In the Keplerian orbit model, the satellite orbit is an ellipse, with eccentricity defining the 'shape' of the ellipse. When e=0, the ellipse is a circle. When e is very near 1, the ellipse is very long and skinny. Source: NASA (http://earthobservatory.nasa.gov/Glossary)
