NGC 3430
Galaxy in the constellation Leo Minor
From Wikipedia, the free encyclopedia
NGC 3430 is a barred spiral galaxy in the constellation of Leo Minor. Its velocity with respect to the cosmic microwave background is 1,869 ± 20 km/s, which corresponds to a Hubble distance of 89.9 ± 6.4 Mly (27.57 ± 1.95 Mpc).[1] In addition, 22 non-redshift measurements give a distance of 85.97 ± 3.77 Mly (26.359 ± 1.157 Mpc).[2] It was discovered by German-British astronomer William Herschel on 7 December 1785.[3]

NGC 3430 is classified as a well-known example of an SAc spiral galaxy with no central bar structure but has spiral arms found open and clear-defined.[4] Moreover, it is also a Wolf-Rayet galaxy, with star-forming regions[5] and forms a pair with NGC 3424, a nearby starburst galaxy.[6] According to a 1997 study presented by researchers, these galaxies are clearly showing signs of tidal interaction.[7]
