Glossary term: Constelación
Description: En términos técnicos modernos, una constelación es un segmento poligonal de la esfera celeste. La Unión Astronómica Internacional ha dividido toda la esfera celeste en 88 regiones: las constelaciones. Este sistema se basa en las que se utilizaban en la antigua Grecia, a las que se han añadido otras más recientes, sobre todo en el hemisferio sur. Cada una de las 88 constelaciones ocupa una parte determinada del cielo y, por tanto, cada uno de los cuerpos celestes, desde las estrellas a las galaxias, pasando por las nebulosas, etc., puede asociarse a una constelación. El Zodíaco son 13 constelaciones que se superponen a la eclíptica (la trayectoria anual trazada por el Sol a través de la esfera celeste). Las 13 constelaciones son: Ofiuco, Sagitario, Capricornio, Acuario, Piscis, Aries, Tauro, Géminis, Cáncer, Leo, Virgo, Libra y Escorpio.
Las constelaciones contienen agrupaciones de estrellas (asterismos) que sugieren un patrón visto desde la Tierra. Estos patrones se describen imaginariamente como representaciones de seres humanos, animales u otros objetos reconocibles.
