NGC 2719 is a Magellanic irregular galaxy in the constellation of Lynx. Its velocity with respect to the cosmic microwave background is 3302 ± 16 km/s, which corresponds to a Hubble distance of 158.8 ± 11.2 Mly (48.70 ± 3.42 Mpc).[1] In addition, one non redshift measurement gives a distance of 154 Mly (47.2 Mpc).[2] The galaxy was discovered by German-British astronomer William Herschel on 28 March 1786.[3]
Together with the galaxy PGC 25284 (also known as NGC 2719A), NGC 2719 is listed in Halton Arp's Atlas of Peculiar Galaxies as Arp 202.[1] The galaxy pair is also listed as Holm 105 in Erik Holmberg's A Study of Double and Multiple Galaxies Together with Inquiries into some General Metagalactic Problems, published in 1937.[4]
One supernova has been observed in NGC 2719: SN 2024xkd (type II, mag. 18.84) was discovered by GOTO on 6 October 2024.[5]
