NGC 128 is a lenticular galaxy in the constellation Pisces. It is approximately 190 million light-years from earth and has a diameter of about 165,000 light years.
NGC 128 is the largest member, and the namesake of the NGC 128 group which also includes the galaxies NGC 127 and NGC 130. NGC 128 has a strong tidal bridge with NGC 127 and there is evidence of interaction between all three galaxies in the group. NGC-128 has a noticeable X- shape that is likely to be caused by gravitational effects of the other two galaxies.
NGC 125 lower right of center and NGC 126 lower left of center are both showing strong tidal effects too.
The redshift of the group members are in the range of 4000-5000 km/s showing their relatively close arrangement.
