Objeto: M52<\/strong><\/p>\n\n\n\n

Constelaci\u00f3n: Cassiopeia
Fecha: 1994.09.04 | Hora: 3:50 UT
Lugar de observaci\u00f3n: Hacienda La Esperanza, Manat\u00ed, PR<\/p>\n\n\n\n

Tipo de objeto: C\u00famulo abierto, clase E
Nombre: (NGC 7654)
Magnitud: 6.9 | Tama\u00f1o: 13′
R.A. 23h24.2m | Dec. +61\u00b035′
\u00c9poca: 2000.0<\/p>\n\n\n\n

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

Espa\u00f1ol:<\/strong> A pesar de que este c\u00famulo, M52, es peque\u00f1o, tiene una apariencia muy atractiva. El punto que atrae la atenci\u00f3n es la estrella brillante que queda en una de las “esquinas”, mientras que la concentraci\u00f3n de estrellas tenues est\u00e1 ubicada hacia el lado contrario. Las estrellas parecen ser todas blancas, y muchas de ellas son bastante tenues (y, visualmente peque\u00f1as). Acompa\u00f1a a M52 otro c\u00famulo abierto, poco conocido y de poca densidad de estrellas: Czernik 43 (se aprecia, en el dibujo, abajo, a la izquierda). Este otro es visible en el mismo campo de visi\u00f3n (de menos de 1\u00ba) de M52.<\/p>\n\n\n\n

English:<\/strong> Although M52 is a small cluster, its appearance is very attractive. The point that captures the attention is the bright star that lies in one of the “corners”, while the concentration of dim stars is located to the opposite side of it. All stars appear white and quite dim (and, visually small). Another open cluster accompanies M52: Czernik 43 (visible in the sketch, lower left); it is little known and has a low star density. It is visible in the same field of view (less than 1\u00ba) of M52.<\/p>\n\n\n\n

Comentarios de Messier en 1784:<\/strong>  C\u00famulo de estrellas bien peque\u00f1as, mezclado con nebulosidad, que solo se puede ver con un anteojo acrom\u00e1tico. Fue observando el cometa que apareci\u00f3 este a\u00f1o que M. Messier vio este c\u00famulo que estuvo cerca del cometa el 7 de septiembre de 1774; est\u00e1 debajo de la estrella d<\/em> de Cassiopea: esta estrella d<\/em> sirvi\u00f3 para determinar el c\u00famulo de estrellas y el cometa. <\/p>\n\n\n\n
