Encyclopedic overview
NGC 7648 is a lenticular galaxy in the constellation Pegasus. It was discovered on October 18, 1784, by the astronomer William Herschel but also observed by astronomers Heinrich d'Arrest and Édouard Stephan. The redshift of the galaxy is estimated to be (z) 0.011. This galaxy has also been designated as IC 1486 when it was observed again by the French astronomer Guillaume Bigourdan.
The nucleus of the galaxy has been described to shine brightly in ultraviolet rays, thus being listed in the Markarian catalogue as MRK 531.
