The Sculptor Galaxy (NGC 253) is a disk galaxy.

Adisc galaxy (ordisk galaxy) is a galaxy characterized by a galactic disc. This is a flattened circular volume of stars that are mainly orbiting the galactic core in the same plane.[1] These galaxies may or may not include a central non-disc-like region (agalactic bulge).[2] They will typically have an orbiting mass of gas and dust in the same plane as the stars. Interactions with other nearby galaxies can perturb and stretch the galactic disk.

Disc galaxy types include:

Galaxies that are not disc types include:
