Keywords: messier 106 messier106 m106 Credit: SDSS/Giuseppe Donatiello J2000 RA 12h 18m 57.5s Dec +47° 18′ 14″ Messier 106 (NGC 4258) is a spiral galaxy in Canes Venatici. It was discovered by Pierre Méchain in 1781. M106 is at a distance of about 23 million light-years. It is also a Seyfert II galaxy. Due to x-rays and unusual emission lines detected, it is suspected that part of the galaxy is falling into a supermassive black hole in the center. NGC 4217 is a possible companion galaxy.
