NGC 596is anelliptical galaxyin theconstellation Cetus.The galaxy lies 65 million light years away from Earth, which means, given its apparent dimensions, that NGC 596 is approximately 60,000 light years across. The galaxy shows an outer envelope and is a merger remnant. The surface brightness profil is smooth and featureless.^[2]The galaxy hosts asupermassive black hole,whose mass is estimated to be 170 million (10^8.24) ${\begin{smallmatrix}M_{\odot }\end{smallmatrix}}$ .^[3]

NGC 596 belongs at the NGC 584 galaxy group, which also includes the galaxiesNGC 584,which lies 25 minutes to the northwest,^[4]NGC 600,NGC 615andNGC 636.^[5]

The galaxy is included in theHerschel 400 Catalogue.It lies about 2 and half degrees northeast fromtheta Ceti.^[6]
