NGC 3504 is a barred spiral galaxy in the constellation Leo Minor. It is a member of the NGC 3504 Group of galaxies, which is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the right edge of the Virgo Supercluster.[3]
There is a large amount of molecular gas centered on the galactic nucleus. Compared with other barred spiral galaxies, NGC 3504 is in an early phase of its evolution.[4]
The mass of NGC 3504 has been difficult to narrow down, but it is believed to be between 2.5*109 M⊙ and 9*109 M⊙.[5]
One supernovae has been observed in NGC 3504: SN 1998cf (type unknown, mag. 15).[6]
