NGC 4546 is a lenticular field galaxy located in the direction of the constellation Virgo,[2] with a total population of globular clusters estimated at 390.[3] It is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster.[4]
Located 45.6 million light years away, with a stellar mass of about 27 billion solar masses,[1] it has a declination of −03° 47' 35" and an average rise of 12 hours, 35 minutes and 29.5 seconds.[5] NGC 4546 was discovered on December 29, 1786 by William Herschel.[6][1][3]
The galaxy appears to be home to a supermassive black hole with a mass of 256 million (± 16 million) times the mass of the Sun.[7] It is estimated to have 390±60 globular clusters.[8]
NGC 4546 appears to have at least 2 companions,[8] NGC 4546-UCD1 and CGCG 014-074.[8]
