Irregular galaxy in the M83 group of galaxies

NGC 5264 NGC 5264, imaged by the Hubble Space Telescope Observation data (J2000 epoch) Constellation Hydra Right ascension 13h 41m 36.683s[1] Declination −29° 54′ 47.25″[1] Redshift 0.001594[2] Heliocentric radial velocity 478 km/s[2] Distance 14.82 ± 0.84 Mly (4.545 ± 0.258 Mpc)[2] Group or cluster Centaurus A/M83 Group (M83 subgroup) Apparent magnitude (V) 12.39[3] Apparent magnitude (B) 12.96[3] Characteristics Type IB(s)m[2] Number of stars 1 billion[5] Size 11000 × 6500 ly (3300 × 2000 pc)[4] Apparent size (V) 2.5′ × 1.5′[4] Other designations DDO 242, UGCA 370, MCG-05-32-066, PGC 48467

**NGC 5264**, also known as **DDO 242**, is an [irregular galaxy](/source/Irregular_galaxy) in the [constellation](/source/Constellation) [Hydra](/source/Hydra_(constellation)). It is part of the M83 subgroup of the [Centaurus A/M83 Group](/source/Centaurus_A%2FM83_Group),[3] located some 15 million [light years](/source/Light_year) (4.5 [megaparsecs](/source/Megaparsec)) away.[2] The galaxy was discovered on 30 March 1835 by [John Herschel](/source/John_Herschel), and it was described as "very faint, pretty large, round, very little brighter middle" by [John Louis Emil Dreyer](/source/John_Louis_Emil_Dreyer), the compiler of the [New General Catalogue](/source/New_General_Catalogue).[6]

NGC 5264 was imaged by the [Hubble Space Telescope](/source/Hubble_Space_Telescope) in 2016. The galaxy is relatively small: it is a [dwarf galaxy](/source/Dwarf_galaxy), a type of galaxy much smaller than normal [spiral galaxies](/source/Spiral_galaxies) and [elliptical galaxies](/source/Elliptical_galaxies). In fact, it is only 11000 [light years](/source/Light_years) (3300 [parsecs](/source/Parsecs)) wide at its widest;[4] our own galaxy, [Milky Way](/source/Milky_Way), in comparison, is about ten times larger.[7] Dwarf galaxies like these usually have about a billion stars. NGC 5264 also is relatively blue-coloured; this is from it [interacting](/source/Interacting_galaxy) with other galaxies, supplying it with gas for [star formation](/source/Star_formation).[5]
