NGC 2719 is aMagellanicirregular galaxy in theconstellation ofLynx. Its velocity with respect to thecosmic microwave background is 3302 ± 16 km/s, which corresponds to aHubble distance of 158.8 ± 11.2 Mly (48.70 ± 3.42 Mpc).[1] In addition, onenon redshift measurement gives a distance of 154 Mly (47.2 Mpc).[2] The galaxy was discovered by German-British astronomerWilliam Herschel on 28 March 1786.[3]
Together with the galaxy PGC 25284 (also known as NGC 2719A), NGC 2719 is listed inHalton Arp'sAtlas of Peculiar Galaxies asArp 202.[1] The galaxy pair is also listed asHolm 105 inErik Holmberg'sA Study of Double and Multiple Galaxies Together with Inquiries into some General Metagalactic Problems, published in 1937.[4]
Onesupernova has been observed in NGC 2719: SN 2024xkd (type II, mag. 18.84) was discovered byGOTO on 6 October 2024.[5]
