The eccentricity of an orbit can be calculated from the orbital state vectors as the magnitude of the eccentricity vector: $${\displaystyle e=\left \mathbf {e} \right }$$ where: e is the eccentricity vector ("Hamilton's vector"). For elliptical orbits it can also be calculated from the periapsis and apoapsis since … See more In astrodynamics, the orbital eccentricity of an astronomical object is a dimensionless parameter that determines the amount by which its orbit around another body deviates from a perfect circle. A value of 0 is a See more The word "eccentricity" comes from Medieval Latin eccentricus, derived from Greek ἔκκεντρος ekkentros "out of the center", from ἐκ- ek-, "out of" + κέντρον kentron "center". … See more The mean eccentricity of an object is the average eccentricity as a result of perturbations over a given time period.
