NGC 4546

NGC 4546 is a lenticular field galaxy located in the direction of the constellation Virgo,[1] with a total population of globular clusters estimated at about 390.[2] Located 45.6 million light years away, with a stellar mass of about 27 billion solar masses,[3] it has a declination of -03 ° 47 '35 "and an average rise of 12 hours, 35 minutes and 29.5 seconds.[4] NGC 4546 was discovered on December 29, 1786 by William Herschel.[5][3][2]
