IC 1189 is a S0-a lenticular galaxy with a ring structure [1] located in Hercules. [2] [3] It is located 557 million light-years away from the Solar System and has an approximate diameter of 145,000 light-years. [4] IC 1189 was discovered on June 7, 1888, by Lewis Swift. [5] [6] It is a member of the Hercules Cluster. [7] [8] [9]

IC 1189 has an active galactic nucleus and is classified as a starburst galaxy [4] meaning to say, it is a powerhouse star factory making stars at a rate hundred of times greater compared to the Milky Way. [10] Additionally, it falls into the Markarian galaxies category as Mrk 300, in which its core shines in ultraviolet rays. [11]
