NGC 4596is abarred lenticular galaxylocated about 55 millionlight-yearsaway[2]in the constellationVirgo.[3]NGC 4596 was discovered by astronomerWilliam Herschelon March 15, 1784.[4]NGC 4596 is a member of theVirgo Cluster[5][6]and has an inclination of about 38°.[7]
Physical characteristics
[edit]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.[8]
Supermassive black hole
[edit]NGC 4596 has asupermassive black holewith an estimated mass of 78 million suns (7.8×107M☉).[9][10][11]
