NGC 3950 is an elliptical galaxy of type E,[1] in Ursa Major. Its redshift is 0.074602,[2] meaning NGC 3950 is 1.03 billion light-years or 316 Mpc from Earth, which is within the Hubble distance values.[3] This high redshift makes NGC 3950 one of the furthest New General Catalogue objects.[4]

NGC 3950 has apparent dimensions of 0.30 x 0.3 arcmin, meaning the galaxy is 90,000 light-years across.[5] It was discovered by Lawrence Parsons[6][7] on April 27, 1875, and he described it as, "extremely faint, 2.6 arcmin north of h 1009".[6]

In a research article published in 1990,[8] NGC 3950 was believed to be a dwarf galaxy, and a close companion of a larger spiral galaxy, NGC 3949.[9] But further research involving measuring its redshift in 2005 showed NGC 3950 is much further away in the background.[10] Together with NGC 3949, they both form an optical galaxy pair called HOLM 301.[11]
