A measure of the lack of coincidence of longitudinal axes of a circular cross-sectional wire and its surrounding circular cross-sectional insulation It is expressed as the percentage ratio of the distance between wire and insulation centers to the difference between wire and insulation radii
The eccentricity of an ellipse (orbit) is the ratio of the distance between its focii and the major axis The greater the eccentricity, the more 'flattened' is the ellipse
Eccentricity of a rotational ellipsoid is a generalization of the ellipse eccentricity It is defined as a square root of one minus square of the semiaxes ratio For a prolate ellipsoid, c is the rotational semiaxis of the ellipsoid, and a is the semiaxis perpendicular to it
Eccentricity is a measure of how circular a satellite's orbit is For a perfectly circular orbit the eccentricity is zero; elliptical orbits have eccentricities between zero and one The higher the eccentricity, the more "squashed" the orbit is
The ratio of the distance of the center of the orbit of a heavenly body from the center of the body round which it revolves to the semi-transverse axis of the orbit
(A-B)/A, where A and B are the lengths of the semi-major and semi-minor axes, respectively, of the orbit The eccentricity (e) of a circular orbit is 0, because A=B An ellipse has e<1 A Parabolic orbit has e=1 A hyperbolic (unbound, or positive energy) orbit has negative e
Number between 0 and 1, gauging the elongation of elliptic orbit The eccentricity e of the orbital ellipse is one of the "orbital elements" characterizing it
Eccentricities are ways of behaving that people think are strange, or habits or opinions that are different from those of most people. We all have our eccentricities. = peculiarity
strange and unconventional behavior a circularity that has a different center or deviates from a circular path (geometry) a ratio describing the shape of a conic section; the ratio of the distance between the foci to the length of the major axis; "a circle is an ellipse with zero eccentricity
The ratio of the distance from the center of an ellipse to its focus to the semimajor axis e = (1-b2/a2)-1/2 where a and b are the semimajor and semiminor axes of the ellipse
(geometry) a ratio describing the shape of a conic section; the ratio of the distance between the foci to the length of the major axis; "a circle is an ellipse with zero eccentricity"
The measure of how elliptical or circular is an orbit The eccentricity is equal to (1-b²/a²)1/2, where a and b are the major and minor axes of the elliptical orbit Circular orbits have e=0, elliptical orbits have 0<e<1, radial and parabolic orbits have e=1, and hyperbolic orbits have e>1
(aka ecce or E0 or e) One of six Keplerian elements, it describes the shape of an orbit In the Keplerian orbit model, the satellite orbit is an ellipse, with eccentricity defining the "shape" of the ellipse When e=0, the ellipse is a circle When e is very near 1, the ellipse is very long and skinny
Description of the shape of a satellite's orbit A circular orbit has an eccentricity of 0 0, the closer to 1 0 the eccentricity, the more elliptical an orbit is Most artificial satellite orbits have an eccentricity less than 0 01, essentially circular
(pronounce: ex-sen-trih-sih-tee) eccentricus, from ex = [Latin] out, and centrum = [Latin] center The eccentricity of an orbit is one of the orbital elements It is a number that indicates how much the orbit deviates from a circle A circular orbit has an eccentricity equal to zero An elliptical orbit has an eccentricity between zero and one In this case, the eccentricity is equal to the difference between the lengths of the long and short axes of the ellipse, divided by the sum of those lengths A parabolic orbit has an eccentricity of one, and a hyperbolic orbit has an eccentricity larger than one Orbits with eccentricities less than one are closed, so the objects in such orbits return to the same position regularly Orbits with eccentricities greater or equal to one are open, which means that objects in such orbits never return to the same position
measures how far from a circular shape an ellipse is Numerically, the eccentricity e = 1 -- (perihelion / semi-major axis) The eccentricity e = 0 for a circle and e = nearly one (1) for very long, skinny ellipses
The amount by which an orbit deviates from a perfect circle: e = c/a, where c is the distance from the center to the focus and a is the semi-major axis In the Solar System, e = 1 - (q/a), where q is the perihelion distance
