NGC 3504 is a barred spiral galaxy in the constellation Leo Minor. It has a Hubble distance corresponding to 88 million light-years[3] and was discovered by William Herschel in 1785.[4]
The luminosity class of NGC 3504 is I-II, with a broad HI line containing regions of ionized hydrogen. Additionally, it is classfied as a starburst galaxy.[5]
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.[6]
