NGC 5612 is a spiral galaxy in the constellation of Apus. Its velocity with respect to the cosmic microwave background is , which corresponds to a Hubble distance of . Additionally, two non-redshift measurements give a closer mean distance of . It was discovered by British astronomer John Herschel on 23 May 1835.
NGC 5612 has a possible active galactic nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.
LDC 1118 group NGC 5612 belongs to the 6 member galaxy group known as LDC 1118. The other galaxies in the group include , , , , and LEDA 5061296.
Supernova One supernova has been observed in NGC 5612: SN 2004ch (TypeII, mag. 16) was discovered by the Perth Automated Supernova Search on 28 May 2004.
