[Sculptor Group Galaxies; AAO]

The Sculptor Group of Galaxies (also South Polar Group)

This is the closest group of galaxies to our Local Group, at only about 10 million light years distance. It is named the Sculptor Group as it is centered in the Southern constellation Sculptor, and South Polar Group as its members are grouped around the South galactic pole (which is at RA 00:51.4, Dec -27:07 (2000.0)).

The group is dominated by bright NGC 253, the Sculptor or Silver Coin Galaxy, one of the brightest galaxies beyong the Local Group in the skies. All the group's members are listed in the following:

(*) indicates membership according to Bryan Miller's research; see his photo collection

Moreover, NGC 45 and IC 5332 were once dealt as a possible member of this group of galaxies, but ttheir larger redshift (504 km/s for NGC 45, 706 km/s for IC 5332 compared to about 90-250 km/s for the larger member galaxies) indicates that these galaxies are more probably background objects.

The first evidence of intergalactic matter was discovered in the Sculptor group of galaxies in 1974, in intergalactic space between NGC 55 and NGC 300.
