In celestial navigation, lunar distance is the angular distance between the Moon and another celestial body. The lunar distances method uses this angle, also called a lunar, and a nautical almanac to calculate Greenwich time if so desired, or by extension any other time. That calculated time can be used in solving a spherical triangle. The theory was first published by Johannes Werner in 1524, before the necessary almanacs had been published. A fuller method was published in 1763 and used until about 1850 when it was superseded by the marine chronometer. A similar method uses the positions of the Galilean moons of Jupiter.

  • Dins l'entorn de la navegació astronòmica, la distància lunar a un astre determinat és l'angle (en graus) entre la Lluna i aquest cos celeste. El navegant pot utilitzar una distància lunar i l'almanac nàutic per calcular l'hora GMT (Greenwich Mean Time). Durant els segles xviii i xix aquest mètode es feia servir per calcular la longitud sense tenir un cronòmetre nàutic a bord. (ca)
  • Als Monddistanz (engl. lunar distance) wird der Winkelabstand des Mondes zu hellen Himmelskörpern (Fixsternen, Sonne oder Planeten) bezeichnet, die in der Nähe seiner Bahn am Himmel liegen. Durch Messung von Monddistanzen zur Bestimmung der Zeit an einem Bezugsmeridian konnte ab Mitte des 18. Jahrhunderts auf Schiffen indirekt die geografische Länge des Schiffsorts errechnet werden (Längenbestimmung, Längenproblem). (de)
  • En navegación astronómica, la distancia lunar a otro astro es el ángulo entre la Luna y ese otro cuerpo celeste. No se debe confundir con la distancia de la Tierra a la Luna, que produce una variación en el tamaño aparente de la Luna pero no sirve para la navegación. El navegante puede usar una distancia lunar y el almanaque náutico para calcular la hora GMT: Greenwich time. En el siglo XVIII y XIX este método se usaba para calcular la longitud sin un cronómetro marino a bordo. (es)
