NGC 2950 is a lenticular galaxy in Ursa Major about 60 million light years from the Milky Way. It was discovered in 1790 by the Anglo-German astronomer William Herschel.[1]
NGC 2950 is a field galaxy, it is not part of a galaxy cluster or galaxy group, and thus is gravitationally isolated.[2] Measures that do not rely on redshift give a distance of 18,733 ± 3,210 Mpc (∼61,1 million astronomical units)[3], which is within the distance calculated by redshift.
NGC 2950 hosts two nested stellar bars; the rotation frequency of the secondary bar is higher than that of the primary one.[4]
