NGC 3449 is a spiral galaxy in the constellation of Antlia. Its velocity with respect to the cosmic microwave background is 3,609±17 km/s, which corresponds to a Hubble distance of 173.6 ± 12.2 Mly (53.23 ± 3.74 Mpc).[1] However, 20 non-redshift measurements give a closer mean distance of 151.97 ± 3.98 Mly (46.595 ± 1.221 Mpc).[2] It was discovered by British astronomer John Herschel on 29 April 1834.[3][4]
NGC 3449 group
[edit]NGC 3449 is the namesake of a trio of galaxies called the NGC 3449 group (also known as LGG 222). The other two galaxies are ESO 437-67 and ESO 437-65.[5][6]
