NGC 5930 is a 12.2 mag bright barred spiral galaxy of the Hubble type SBb / pec in the constellation Bärenhüter and about 123 million light years from the Milky Way.Together with the much smaller galaxy NGC 5929 it forms the interacting constellation Arp 90 .
Halton Arp organized his catalog of unusual galaxies into groups according to purely morphological criteria. This galaxy belongs to the class spiral galaxies with a large companion of high surface brightness on one arm (Arp catalog) .
The galaxy was discovered on March 18, 1787 by Wilhelm Herschel with an 18.7-inch reflecting telescope, who described it as "pB, pL, iE, easily resolvable".
