NGC 1620 is an intermediate spiral galaxy in the constellation of Eridanus. Its velocity with respect to the cosmic microwave background is 3,455 ± 4 km/s, which corresponds to a Hubble distance of 51.0 ± 3.6 Mpc Mpc (∼166 million light-years).^[1] It was discovered by German-British astronomer William Herschel on 1 January 1786.

Two supernovae have been observed in NGC 1620: SN 2009K (type IIb, mag. 14.9)^[2] and SN 2023crx (type Ib, mag. 18.6).^[3]

According to A.M. Garcia, the galaxy NGC 1620 is part of the NGC 1589 Group (also known as LGG 117) that includes at least 8 other galaxies: NGC 1586, NGC 1587, NGC 1588, NGC 1589, UGC 3054, UGC 3058, UGC 3072 and UGC 3080.^[4]
