Eccentricity of a straight line
WebAnswer (1 of 2): If you specify non-degenerate conics, then I guess there's no answer. If you allow degenerate conics, then I can think of 3 cases: 1. Degenerate hyperbola, when eccentricity is infinite. This will be two coincident lines. 2. Degenerate ellipse, an ellipse that is squashed all th... WebNov 3, 2024 · Eccentricity is the extent to which an orbit deviates from a circle, and it ranges from 0 (a circle) to nearly 1 (almost a straight line). Although using that number you can tell Earth's orbit is ...
