What's the difference between ellipse and plane?

Ellipse


Definition:

  • (n.) An oval or oblong figure, bounded by a regular curve, which corresponds to an oblique projection of a circle, or an oblique section of a cone through its opposite sides. The greatest diameter of the ellipse is the major axis, and the least diameter is the minor axis. See Conic section, under Conic, and cf. Focus.
  • (n.) Omission. See Ellipsis.
  • (n.) The elliptical orbit of a planet.
