NGC 3430

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 ± 20km/s, which corresponds to a Hubble distance of. In addition, 22 non-redshift measurements give a distance of. It was discovered by German-British astronomer William Herschel on 7 December 1785.
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. Moreover, it is also a Wolf-Rayet galaxy, with star-forming regions and forms a pair with NGC 3424, a nearby starburst galaxy. According to a 1997 study presented by researchers, these galaxies are clearly showing signs of tidal interaction.
