NGC 7606 is aspiral galaxy located in the constellationAquarius. It is located at a distance of about 100 millionlight years from Earth, which, given its apparent dimensions, means that NGC 7606 is about 200,000 light years across. It was discovered byWilliam Herschel on September 28, 1785.[3][4] The galaxy is included in theHerschel 400 Catalogue. It lies 45 arcminutes northeast frompsi2 Aquarii. It can be seen with a 4 inchtelescope but its visibility is greatly affected bylight pollution.[5]
NGC 7606 is a spiral galaxy seen on inclination. It has a bright nucleus surrounded by a prominent bulge, which is seen elliptical due to the inclination. Nobar has been observed.[6] A ring with an apparent diameter of 0.85 arcminutes has been detected at the central part of the galaxy.[7] The galaxy features two main arms, that can be traced for nearly 360°, and several arm fragments.[6] The arms are smooth and rather tight, although not as tightly wound as the ones ofNGC 488.[8] Few bright spots have been observed in the arms.[6] The galaxy is found to host asupermassive black hole, whose mass based on bulge velocity dispersion σ is estimated to be 15-22 millionM☉.[9][10] NGC 7606 is an isolated galaxy.[11]
