It is related to the position … WebJan 22, 2024 · Often, the eccentricity is used which is defined as e = 1 − b 2 a 2 So for a circle with a = b, the eccentricity is 0, and for the edge case, a very long ellipse with a → ∞, we get a parabola which hence has an eccentricity of 1. Now, what would a trajectory look like with an eccentricity larger than 1?
