NGC 839 is a lenticular galaxy located in the constellation Cetus. It was discovered November 28, 1785 in a sky survey by Wilhelm Herschel. [3] It is one of the galaxies that are part of the quadruplet family HGC 16, along with the unbarred lenticular galaxy NGC 838. [2]
NGC 839 is a luminous infrared galaxy (LIRG) that shows signs of high amounts of star formation; therefore, it is also classified as a starburst galaxy. [4] It is similar in appearance to Messier 82, suggesting a similar formation history. [4]
