The luminosity class of IC 2560 is II [5] with a broad HI line [6] containing regions of ionized hydrogen. Moreover, IC 2560 is an active Type 2 Seyfert Galaxy. [7] It has a distinct bar structure in the center with the supermassive black hole at the core having a mass of 4.4+4.4
−2.2×106  M☉ . [8]

One supernova has been observed in IC 2560. SN 2020ejm (type Ia, mag. 16) was discovered by the Distance Less Than 40 Mpc Survey (DLT40) on 11 March 2020. [9]

NGC 3223 group

IC 2560 is a member of the NGC 3223 Group. There are 15 other galaxies in the group including NGC 3223, NGC 3224, NGC 3258, NGC 3268, NGC 3289, IC 2552 and IC 2559. [10] Together, the group is part of the Antlia Cluster. [11]
