  • All the horizon round Invested with bright rays. --Milton. [1913 Webster]
  • 2. (Astron.) (a) A plane passing through the eye of the spectator and at right angles to the vertical at a given place; a plane tangent to the earth's surface at that place; called distinctively the sensible horizon. (b) A plane parallel to the sensible horizon of a place, and passing through the earth's center; -- called also rational horizon or celestial horizon. (c) (Naut.) The unbroken line separating sky and water, as seen by an eye at a given elevation, no land being visible. [1913 Webster]

  • Apparent horizon. See under Apparent.
  • Artificial horizon, a level mirror, as the surface of mercury in a shallow vessel, or a plane reflector adjusted to the true level artificially; -- used chiefly with the sextant for observing the double altitude of a celestial body.
  • Celestial horizon. (Astron.) See def. 2, above.
  • Dip of the horizon (Astron.), the vertical angle between the sensible horizon and a line to the visible horizon, the latter always being below the former.
  • Rational horizon, and Sensible horizon. (Astron.) See def. 2, above.
  • Visible horizon. See definitions 1 and 2, above. [1913 Webster]
