  1. Horizon

    The horizon is the apparent line that separates earth from sky, the line that divides all visible directions into two categories: those that intersect the Earth's surface, and those that do not. At many locations, the true horizon is obscured by trees, buildings, mountains, etc., and the resulting intersection of earth and sky is called the visible horizon. When looking at a sea from a shore, the part of the sea closest to the horizon is called the offing. The word horizon derives from the Greek "ὁρίζων κύκλος" horizōn kyklos, "separating circle", from the verb ὁρίζω horizō, "to divide", "to separate", and that from "ὅρος", "boundary, landmark".

Horizon′tal, pertaining to the horizon: parallel to the horizon: level: near the horizon: measured in a plane of the horizon.—n. Horizontal′ity.—adv. Horizon′tally.—Artificial horizon, a small trough containing quicksilver, the surface of which affords a reflection of the celestial bodies. [Fr.,—L.,—Gr. horizōn (kyklos), bounding (circle), horizein, to bound—horos, a limit.]

Dictionary of Nautical Terms

  1. horizon

    The apparent or visible circle which bounds our vision at sea; it is that line which is described by the sky and water appearing to meet. This is designated as the sensible horizon; the rational, or true one, being a great circle of the heavens, parallel to the sensible horizon, but passing through the centre of the earth.

Military Dictionary and Gazetteer

  1. horizon

    (Gr. orizo, I bound or terminate). In astronomy and geography, is the plane of the great circle of the sphere, dividing the visible from the invisible hemisphere. The horizon is either sensible or rational. The sensible horizon is a plane which is a tangent to the earth’s surface at the place of the spectator, extended on all sides till it is bounded by the sky; the rational horizon is a plane parallel to the former, but passing through the centre of the earth. Both the sensible and rational horizon are relative terms, and change with every change of the spectator’s position on the surface of the earth; in all cases they are perpendicular to the direction of gravity.
