Webster's Revised Unabridged Dictionary
  • Interesting fact: Because of a large orbital eccentricity, Pluto was closer to the sun than Neptune between January 1979 and March 1999.
    • Eccentric (Astron) A circle described about the center of an elliptical orbit, with half the major axis for radius.
    • Eccentric A circle not having the same center as another contained in some measure within the first.
    • Eccentric (Mach) A disk or wheel so arranged upon a shaft that the center of the wheel and that of the shaft do not coincide. It is used for operating valves in steam engines, and for other purposes. The motion derived is precisely that of a crank having the same throw.
    • Eccentric Deviating from stated methods, usual practice, or established forms or laws; deviating from an appointed sphere or way; departing from the usual course; irregular; anomalous; odd; as, eccentric conduct. "This brave and eccentric young man.""He shines eccentric , like a comet's blaze."
    • Eccentric Deviating or departing from the center, or from the line of a circle; as, an eccentric or elliptical orbit; pertaining to deviation from the center or from true circular motion.
    • Eccentric (Astron) In the Ptolemaic system, the supposed circular orbit of a planet about the earth, but with the earth not in its center.
    • Eccentric Not coincident as to motive or end. "His own ends, which must needs be often eccentric to those of his master."
    • Eccentric Not having the same center; -- said of circles, ellipses, spheres, etc., which, though coinciding, either in whole or in part, as to area or volume, have not the same center; -- opposed to concentric.
    • Eccentric One who, or that which, deviates from regularity; an anomalous or irregular person or thing.
    • Eccentric (Mach) Pertaining to an eccentric; as, the eccentric rod in a steam engine.

    • eccentric Not located or situated in the center; away from the center or axis: as, in botany, lateral embryos and the stipes of some hymenomycetous fungi are said to be eccentric.
    • eccentric In medicine, not originating or existing in the center or central parts; due to peripheral causes: as, eccentric irritation; eccentric convulsions (that is, convulsions due to peripheral irritation).
    • eccentric Not coincident as regards center; specifically, in geometry, not having the same center: applied to circles and spheres which have not the same center, and consequently are not parallel: opposed to concentric, having a common center.
    • eccentric Not coincident as regards course or aim; tending to a different end or result; devious.
    • eccentric Deviating, or characterized by deviation, from recognized, stated, or usual methods or practice, or from established forms, laws, etc.; irregular; erratic; odd: as, eccentric conduct; an eccentric person.
    • eccentric Of or pertaining to an eccentric: as, the eccentric anomaly of a planet; the eccentric rod of a steam-engine.
    • eccentric In senses 3 and 6 sometimes written excentric.
    • n eccentric In ancient astronomy, a circle having its center remote from the earth and carrying an epicycle which in its turn was supposed to carry a planet.
    • n eccentric In mod. astron., a circle described about the center of an elliptical orbit, with half the major axis for radius.
    • n eccentric In mech., a device for converting a regular circular motion into an irregular reciprocating rectilinear motion. It acts upon the body moved by it through its perimeter like a cam, with which it is sometimes classed; but all its peculiarities of motion are essentially those of a crank-motion, and it may be considered as a crank having a wrist of larger diameter than the throw. In the steam-engine it is a disk fitted to the shaft, with its center placed at one side of the center of the shaft, and it acts to convert the rotary motion of the shaft into the reciprocating motion of the valve-gear of the cylinder, and thus to make the engine self-acting. (see link-motion, reversing-gear, and cut-off.) In this sense sometimes written excentric.
    • n eccentric One who or that which is irregular or anomalous in action; a person of eccentric habits.
    • eccentric In astronomy, noting orbital motion which is not in a circle around the center of attraction; as applied to curves generally, deviating from circularity, as the ellipse and hyperbola.

    • n Eccentric (mech.) a contrivance for taking an alternating rectilinear motion from a revolving shaft: an eccentric fellow
