NGC 3521 is a flocculent[4] intermediate spiral galaxy located around 26[4] million light-years away from Earth in the constellation Leo. It has a morphological classification of SAB(rs)bc,[3] which indicates that it is a spiral galaxy with a trace of a bar structure (SAB), a weak inner ring (rs), and moderate to loosely wound arm structure (bc).[5] The bar structure is difficult to discern, both because it has a low ellipticity and the galaxy is at a high inclination[3] of 72.7° to the line of sight.[4] The relatively bright bulge is nearly 3/4 the size of the bar, which may indicate the former is quite massive.[3] The nucleus of this galaxy is classified as an HII LINER,[6] as there is an H II region at the core and the nucleus forms a low-ionization nuclear emission-line region.
