WebPlanet Eccentricity. Eccentricity is the deviation of a planet’s orbit from circularity — the higher the eccentricity, the greater the elliptical orbit. An ellipse has two foci, which are the points inside the ellipse where the … Mercury has the greatest orbital eccentricity of any planet in the Solar System ( e = 0.2056 ). Such eccentricity is sufficient for Mercury to receive twice as much solar irradiation at perihelion compared to aphelion. Before its demotion from planet status in 2006, Pluto was considered to be the planet with the most … 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". "Eccentric" first appeared in English in 1551, with the definition "...a circle in which the … See more The eccentricity of Earth's orbit is currently about 0.0167; its orbit is nearly circular. Venus and Neptune have even lower eccentricities. Over hundreds of thousands of years, the … See more Orbital mechanics require that the duration of the seasons be proportional to the area of Earth's orbit swept between the solstices and equinoxes, so when the orbital eccentricity is … See more In a two-body problem with inverse-square-law force, every orbit is a Kepler orbit. The eccentricity of this Kepler orbit is a non-negative number that defines its shape. The eccentricity may take the following values: • See more 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 … See more The mean eccentricity of an object is the average eccentricity as a result of perturbations over a given time period. Neptune currently has an instant (current epoch) … See more
