NGC 4653 is an intermediate spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 2,960±24 km/s, which corresponds to a Hubble distance of 142.4 ± 10.0 Mly (43.66 ± 3.08 Mpc).[1] However, two non-redshift measurements give a closer distance of 131.11 ± 3.59 Mly (40.200 ± 1.100 Mpc).[2] It was discovered by German-British astronomer William Herschel on 11 April 1787.[3]
NGC 4642 Group
[edit]NGC 4653 is a member of the NGC 4642 Group (also known as LDC 913). This trio of galaxies includes NGC 4642 and NGC 4690.[4][5] A study published in 2022 claims that NGC 4653 and NGC 4642 form a physical pair, separated by about 50 kpc, and that there is a high probability of a merger in the near future.[6]
Supernovae
[edit]Three supernovae have been observed in NGC 4653:
- SN 1999gk (type II, mag. 15.7) was discovered by Perry Berlind on 15 December 1999.[7][8]
- SN 2009ik (type Ia, mag. 15.3) was discovered by Berto Monard on 22 August 2009.[9][10]
- SN 2025mqc (type Ib, mag. 18.78) was discovered by ATLAS on 31 May 2025.[11]
