NGC 5970 is an active bar-spiral galaxy of the Hubble-type SBc with extensive star formation areas in the constellation Snake north of the celestial equator . It is estimated to be 90 million light years from the Milky Way and about 80,000 light years in diameter. Presumably it forms a gravitationally bound galaxy pair together with IC 1131 . She is the brightest member of the NGC 5970 group ( LGG 401 ).
In the same area of the sky are u. a. the galaxies NGC 5956 and NGC 5957 .
The object was discovered on March 15, 1784 by the astronomer William Herschel with the help of his 18.7-inch mirror telescope and was later included in his New General Catalog by Johan Dreyer .
