NGC 1964 is a barred spiral galaxy in the constellation Lepus. The galaxy lies 65 million light years away from Earth, which means, given its apparent dimensions, that NGC 1964 is approximately 100,000 light years across. At its center lies a supermassive black hole, with estimated mass 2.5 × 107 M☉.[3] The galaxy features two tightly wound inner spiral arms within a disk with high surface brightness and two outer, more open spiral arms that originate near the inner ring. The outer arms feature few small HII regions.[4]

NGC 1964 ist eine Balken-Spiralgalaxie ausgeprägten Spiralarmen vom Hubble-Typ SBb im Sternbild Hase am Nordsternhimmel. Sie ist schätzungsweise 67 Millionen Lichtjahre von der Milchstraße entfernt und hat einen Durchmesser von etwa 130.000 Lichtjahren. Die Galaxie ist Namensgeberin der NGC 1964-Gruppe, zu der weiterhin NGC 1979, IC 2130 und IC 2137 gehören.- [en] NGC 1964
