Eccentricity measures the deviation of the Earth's orbit from a circular orbit. It ranges from 0 for a circular orbit at 1 in a highly elliptical orbit. But the eccentricity of Earth's orbit varies between 0 and 0.06 for every 100 000 years. Image: The eccentricity, obliquity and precession are used within the astronomical theory of paleoclimate The eccentricity of a vertex is the maximal distance between the given vertex and any other vertex in the graph. It gives a measure of how far away a vertex is from the rest of the graph For an ellipse, the eccentricity is the ratio of the distance from the center to a focus divided by the length of the semi-major axis. ( astronomy ) The eccentricity of the conic section ( usually an ellipse ) defined by the orbit of a given object around a reference object ( such as that of a planet around the sun ) An ellipse is a special type of conic section such that the points in an ellipse have their distances from two fixed points known as the focus constant Wheel Graph.
