NGC 3486 is a barred spiral galaxy located about 27.4[3] million light years away in the constellation of Leo Minor. It has a morphological classification of SAB(r)c,[4] which indicates it is a barred spiral with an inner ring and loosely wound arms.[6] This is a borderline, low-luminosity Seyfert galaxy with an active nucleus. However, no radio or X-ray emission has been detected from the core, and it may only have a small supermassive black hole with less than a million times the mass of the Sun.[7]
