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). In addition, 22 non-redshift measurements give a distance of 85.97 ± 3.77 Mly (26.359 ± 1.157 Mpc). It was discovered by German-British astronomer William Herschel on 7 December 1785.

NGC 3430 and NGC 3424 imaged by SDSS

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.

NGC 3396 Group

NGC 3430 is a member of the NGC 3396 group (also known as LGG 218), which includes at least 11 galaxies: NGC 3381 [fr], NGC 3395, NGC 3396, NGC 3424 [fr], NGC 3442 [fr], IC 2604 [de], UGC 5898 [d], PGC 32631, UGC 5934, and UGC 5990 [d].
