NGC 1023 is a barred lenticular spiral galaxy located in the constellation of Perseus at a distance of about 32 million light years: it is the brightest member of the NGC 1023 group, which also includes NGC 891 and NGC 925.
This galaxy is characterized by having a particular type of star cluster, called faint fuzzies, which appear to be a sort of globular clusters, born from the merger of other clusters: this type of cluster has been found only in two other galaxies: NGC 3384 and NGC 5195, the companion of M5. These clusters also have the characteristic of having a relative abundance of neutral hydrogen.
NGC 1023 appears to have a central black hole with a mass between 40 and 60 million solar masses.
NGC 1023 is part of the NGC 1023 Group located in the Virgo Supercluster. The group includes, among others, the galaxies NGC 891, NGC 925, NGC 949, NGC 959, NGC 1003, NGC 1058 and IC 239.
