NGC 4026 is an edge-on lenticular galaxy in the constellation Ursa Major. It is located at a distance of circa 50 million light years from Earth, which, given its apparent dimensions, means that NGC 4026 is about 80,000 light years across. It was discovered by William Herschel on April 12, 1789.
The galaxy hosts a supermassive black hole with estimated mass 108.33±0.109 (166-275 million) M☉.[2]
