NGC 5539 is a large lenticular galaxy in the Boötes constellation.[1][2] It is located 857 million light-years away and was discovered by John Herschel on 24th April, 1830.[3] According to Herschel, he found it quite large and irregular.[3] NGC 5539 is about 273,000 light-years in diameter, meaning it is much larger compared to the Milky Way and its neighbor, the Andromeda Galaxy.[2] It is the brightest cluster galaxy in Abell 1890.[2][4]
It is said NGC 5539 can be classified as a high surface brightness galaxy with a surface brightness value of 11.40 mag/am2.[5]
