Physical characteristics
NGC 4596 has a strong bar with bright ansae at the ends. Two diffuse spiral arms branch off from the ends of the bar and form an inner pseudoring that is well-defined. The spiral arms continue out and fade rapidly in the bright outer disk.{{Cite web|url=http://kudzu.astr.ua.edu/devatlas/NGC_4596______B___________.html|title=NGC 4596 - SB(rs)0/a|website=The De Vaucouleurs Atlas of Galaxies|access-date=2018-03-15}}
