NGC 3073 is a dwarf lenticular galaxy in the constellation Ursa Major.[5][6][7] It is at a distance of about 65 million light-years (20 megaparsecs) from Earth.[3] NGC 3073 was discovered by German-British astronomer William Herschel on 1 April 1790. [8]

NGC 3073 belongs to the NGC 3079 Group (also known as LGG 188), which contains six galaxies.[9] The other galaxies in the group are NGC 3079, UGC 5421, UGC 5479, UGC 5459, and UGC 5460.[10] The galaxies NGC 3073 and NGC 3079 are also listed together as Holm 156 in Erik Holmberg's A Study of Double and Multiple Galaxies Together with Inquiries into some General Metagalactic Problems, published in 1937.[11]
