Eccentricity is a measure of how 'out of round' an ellipse is. If the eccentricity is zero, it is not squashed at all and so remains a circle. If it is 1, it is completely squashed and looks like a line.
Explanation:
The eccentricity of an ellipse is a model of how approximately circular the ellipse. Irregularity is determined by the resulting formula eccentricity = c/a where c is the distance from the middle to the focus of the ellipse a is the range from the center to a vertex.
A flat line has e = infinity. A parabola is the curve /orbit created when e = 1 and is equidistant from a location and a line. When the eccentricity of the orbit is higher than 1.0000, the orbit converts a hyperbola. A complete hyperbola has two moieties and two foci.
Eccentricity is a measure of how 'out of round' an ellipse is. If the eccentricity is zero, it is not squashed at all and so remains a circle. If it is 1, it is completely squashed and looks like a line. Hope this helps. Have a nice day. Feel free to ask more questions.
