NGC 3437 is a barred spiral galaxy in the constellation of Leo. Its velocity with respect to the cosmic microwave background is 1,597±23 km/s, which corresponds to a Hubble distance of 76.8 ± 5.5 Mly (23.56 ± 1.68 Mpc). Additionally, 17 non-redshift measurements give a similar mean distance of 79.12 ± 2.14 Mly (24.259 ± 0.656 Mpc). It was discovered by German-British astronomer William Herschel on 12 March 1784. NGC 3437 is listed as a radio galaxy.
Supernovae and luminous red nova Two supernovae and one luminous red nova have been observed in NGC 3437:
SN 2004bm (Type Ic, mag. 17.5) was discovered by the Lick Observatory Supernova Search (LOSS) on 25 April 2004. NGC 3437−2011OT1 (also named PSN J10523453+2256052 and SNhunt31) (Type LRN, mag. 18.4) was discovered by the Catalina Real-time Transient Survey on 10 January 2011. It was initially suspected of being a luminous blue variable, but later analysis concluded that it was a luminous red nova. SN 2026kie (Type Ic, mag. 18.086) was discovered by ATLAS on 22 April 2026. It had originally been classified as Type Ib, but later analysis concluded it to be Type Ic.
