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

Espa\u00f1ol:<\/strong> M102 parece una versi\u00f3n diminuta y menos definida de M104, en Virgo. La franja que divide la galaxia en dos partes se ve con facilidad. La proximidad de dos estrellas relativamente brillantes le otorga mejor vista (que no tendr\u00eda si se encontrara sola). Generalmente, se considera esta galaxia como el objeto 102 del cat\u00e1logo de Messier (pues hay evidencia que prueba que \u00e9l la observ\u00f3), aunque se sabe, al mismo tiempo, que la entrada hecha por Messier para el objeto 102 se\u00f1ala que se trata de una duplicaci\u00f3n de sus observaciones para M101 (localizada cerca de esta regi\u00f3n). As\u00ed tambi\u00e9n lo atestigua Pierre M\u00e9chain (ver sus notas m\u00e1s abajo).<\/p>\n\n\n\n

English:<\/strong> M102 looks like a tiny and less defined version of M104, in Virgo. The dust lane that divides the galaxy into two parts is easily seen. The proximity of two relatively bright stars gives it a nice view (which it wouldn\u2019t have if it were alone). Generally, this galaxy is considered as object 102 of the Messier catalog (as there is evidence to prove he observed it, although he didn\u2019t include it in his catalog), although at the same time, it is known that Messier’s entry for object 102 indicates that it is a duplication of his observations for M101 (located near this region), as commented by Pierre M\u00e9chain, his friend and observation partner. Review his notes below.<\/p>\n\n\n\n

Comentarios de Messier en 1784:<\/strong> Nebulosa entre las estrellas \u03bf del Boyero y \u03b9 del Drag\u00f3n: es muy d\u00e9bil; cerca de ella hay una estrella de sexta magnitud.<\/p>\n\n\n\n

Comentarios de P. M\u00e9chain:<\/strong> A\u00f1adir\u00e9 solamente que N\u00ba. 101. & 102. en la p. 267. Conocimiento de los tiempos 1784. no son sino una misma nebulosa, que ha sido tomada como dos, por una falla en la carta [celeste].
