The distance of the center of figure of a body, as of an eccentric, from an axis about which it turns; the throw.
Measures how elliptical the earth-sun orbit is, with consequent effects on solar radiation received by the earth. If e is the eccentricity then (1 + e)/(1 - e) is the ratio of the farthest and closest earth-sun distance.

Geometric shape of the Earth's orbit. This shape varies from being elliptical to almost circular.
The state or condition of being eccentric. Deviation from a centre.
The eccentricity is the measure for the deviation of the tube axis of the outside diameter from that of the inner diameter. Eccentricity results from the wall thickness deviation.
The out-of-roundness of a roll, core, or mandrel. Eccentricity usually is expressed as TIR (total indicated runout) in mils. When eccentricity is present, points on the roll surface do not rotate in the same axial circle.
a parameter that specifies the shape of a conic section; one of the standard elements used to describe an elliptic orbit. (See elements, orbital.)
The ratio between the foci and major axis of an ellipse. It can be used to describe the shape of the ellipse.

A measure of the shape of the orbit of a body or ellipse that compares the lengths of the semimajor axis (longest length) and semiminor axis (shortest length). The eccentricity of a circle is zero, while a highly elliptical orbital path of a comet might be 0.9.
Deviation from a common center, for example, the inner and outer walls of a round tube. The difference between the mean wall thickness and minimum or maximum wall thickness at any one cross section. The permissible degree of eccentricity can be expressed by a plus and minus wall-thickness tolerance.
The degree to which the Earth's orbit around the sun varies from a perfect circle - it ranges between about 1% and 5% across a 100,000 year cycle.
a circularity that has a different center or deviates from a circular path
is the departure of an elliptical orbit from a circle. A circle has an eccentricity of 0; a very elongated orbit has an eccentricity approaching 1. The eccentricity of Pluto's orbit has the largest value of all the planets (0.248). The Ecliptic is the plane of the Earth's orbit. Most of the planetary orbits are close to this plane. Pluto's orbit is inclined at an angle of 17.14 degrees to the ecliptic plane - the largest deviation of any planet.
The eccentricity of an orbit is a measure of its departure from a circle. Elliptical orbits have an eccentricity 0 and 1, parabolic paths have an eccentricity =1, and hyperbolic paths have an eccentricity 1.
A measure of how far as orbit diverges from a circle, that is how elliptical it is.
Measure of the departure of an orbit from a perfect circle. A circular orbit has eccentricity, e = 0; an elliptic orbit has 0 e 1; a parabolic orbit has e = 1; and a hyperbolic orbit has e 1.
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.
a measure of the flatness of an ellipse; a ratio of the distance between foci divided by the length of the major axis
The eccentricity measures the relation between maximum distance a ( Aphelion) and minimum distance b ( Perihelion) of an elliptical orbit. The eccentricity measures how far from a circular shape an elliptic orbit is. Eccentricity e = √(a² - b²) / a.
The degree of flattening of an ellipse, measured from 0 to 1. An ellipse with an eccentricity of 0 is a circle. Celestial objects in orbits with large eccentricities (close to 1.0) have highly flattened or elongated orbits.
the extent to which a bodyâ€(tm)s elliptical orbit deviates from a circle
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.
Off centre or out of round condition, such as a roller or cylinder which does not rotate evenly.
A measure of the flatness of an ellipse, equal to the distance between the two foci divided by the length of the major axis.
The amount of separation between the two foci of an ellipse and, hence, the degree to which an elliptical orbit deviates from a circular shape.
a parameter that describes the shape of an orbit; the closer the eccentricity is to zero, the more circular the orbit
Variation in radius of an information track from the true axis of rotation of the disc. May be confused with runout.
The eccentricity of an ellipse (orbit) is the ratio of the distance between its foci and the major axis. The greater the eccentricity, the more 'flattened' is the ellipse.
A measure of the center of a conductor's location with respect to the circular cross-section of the insulation surrounding it, expressed as a percentage of center displacement of one circle within the other.
A measure of the shape of an ellipse, defined as the ratio of the distance between the foci and the length of the major axis. Smaller values indicate greater ellipse elongation or 'out-of-roundness.'
The normal distance between the centroidal axis of a member and the parallel resultant load.: Ratio of virtual eccentricities occurring at the ends of a column or wall under design. The absolute value is always less than or equal to 1.0.
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.
a dimensionless quantity describing the elliptical shape of a planet's orbit
The amount that the earth's revolution deviates from a circular path; the variation of an ellipse from a circle, where a circle has an eccentricity of 0.
Mathematically, the ratio of the distance between the foci of an ellipse, compared to the major axis of the ellipse. For planetary orbits, the variation in distance of a planet from the Sun, expressed as a decimal fraction of the average distance from the Sun. Equal to the distance from the center of the orbit to the Sun, expressed as a fraction of the semi-major axis of the orbit. A planet whose eccentricity is .20 would be 20% closer to the Sun at perihelion, than on the average, and 20% further away at aphelion, than on the average.
Eccentricity is a measure of how an orbit deviates from circular. A perfectly circular orbit has an eccentricity of zero; an eccentricit between0 and 1 represents an elliptical orbit. A parabolic orbit has an eccentricity equal to 1; a hyperbolic orbit has an eccentricity greater than 1. Neptune, Venus, and Earth are the planets with the least eccentric orbits in our solar system. Pluto and Mercury are the planets with the most eccentric orbits in our solar system.
When two diameters share a common center they are said to be concentric. Deviations from theoretical or perfect concentricity are called eccentricity.
A measure of the shape of an ellipse, such as the orbit of a body around a center of mass, that compares the lengths of the semimajor, or longest, axis and the semiminor, or shortest, axis. The eccentricity of a circle is zero, while a highly elliptical orbital path of a comet might be 0.9.

Refers to a factor used to describe the geometric shape of an ellipsis or an elliptical orbit. As eccentric approaches 0 the shape approaches that of a circle as eccentricity approaches 1 the shape approaches a straight line.
The measure of the degree to which an ellipse is not circular; ratio of the distance between the foci to the major axis. The greater the eccentricity, the more 'flattened' is the ellipse.

The distance between the resultant of an applied load and the centroidal axis of the masonry element under load.
In mathematics, eccentricity is a parameter associated with every conic section. It can be thought of as a measure of how much the conic section deviates from being circular. (Or, in lay men's terms, how "not round" it is.)
