prime meridian

meridian

meridian a circle of constant longitude passing through a given place on the earth's surface and the terrestrial poles; in astronomy, a circle passing through the celestial poles and the zenith of a given place on the earth's surface.

Recorded from late Middle English, the word comes via Old French from Latin meridianum (neuter, used as a noun) ‘noon’, from medius ‘middle’ + dies ‘day’. The use in astronomy is due to the fact that the sun crosses a meridian at noon.

meridian

meridian, from Latin medius meaning middle, and dies meaning day, a semi-great circle joining the earth's poles. Meridians, better known as lines of longitude, cross the equator and all parallels of latitude at right angles. Owing to the rotation of the earth, all celestial bodies appear to revolve around the earth towards the west, making one revolution in a day. When the sun crosses an observer's meridian, the local time is midday.
