Descripci\u00f3n<\/h3>\n\n\n\n

Espa\u00f1ol:<\/strong> M40 es una estrella doble en la constelaci\u00f3n de la Osa Mayor (cerca de 1\u00b0 de Delta <\u03b4> Ursa Majoris, la estrella que marca el comienzo del mango de la cacerola), cuya magnitud combinada es de 8.0 (la m\u00e1s brillante de las componentes tiene una magnitud aparente de 9.3). La separaci\u00f3n entre ambas es de 50″. Ambas estrellas son visibles en binoculares (al menos, 10×50).<\/p>\n\n\n\n

English:<\/strong> M40 is a double star in Ursa Major (about 1\u00b0 from Delta <\u03b4> Ursa Majoris, the star that marks the beginning of the handle), whose combined magnitude is 8.0 (the brightest of components has an apparent magnitude of 9.3). The separation between the two stars is 50″. Both stars are visible in 10x50mm binoculars.<\/p>\n\n\n\n

Cometarios de Messier en 1771:<\/strong> La misma noche del 24 al 25 de octubre, busqu\u00e9 la nebulosa que est\u00e1 arriba del dorso de la gran Osa, indicada en el libro de la Figura de los Astros, segunda edici\u00f3n<\/em>: debi\u00f3 tener en 1660, 183\u00b0 32′ 41″ de ascensi\u00f3n recta, y 60\u00b0 20′ 33″ de declinaci\u00f3n boreal. Encontr\u00e9 por medio de esta posici\u00f3n dos estrellas bien cercanas una de la otra y de igual magnitud, alrededor de la novena clase, localizadas en el nacimiento de la cola de la gran Osa; apenas se distinguen con un anteojo ordinario de 6 pies. He aqu\u00ed sus posiciones: ascensi\u00f3n recta, 182\u00b0 45′ 30″, y 59\u00b0 23′ 50″ de declinaci\u00f3n boreal. Es de suponer que Hevelius habr\u00e1 tomado estas dos estrellas por una nebulosa.<\/p>\n\n\n\n

Comentarios de Messier en 1784:<\/strong> Dos estrellas muy cerca una de la otra y muy peque\u00f1as, localizadas en el nacimiento de la cola de la gran Osa: apenas se distingue con un anteojo ordinario de 6 pies. Es buscando la nebulosa localizada arriba de la espalda de la gran Osa, reportada en el libro de la figura de los Astros, que debi\u00f3 tener en 1660, 183\u00b0 32′ 41″ de ascensi\u00f3n recta y 60\u00b0 20′ 33″ de declinaci\u00f3n boreal, que M. Messier no la pudo ver, que \u00e9l ha observado estas dos estrellas.<\/p>\n\n\n\n
