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]
