NGC 178 is a Magellanic spiral [5] galaxy in the constellation of Cetus. The compiler of the New General Catalogue, John Louis Emil Dreyer noted that NGC 178 was "faint, small, much extended 0°, brighter middle". It was discovered on November 3, 1885, by Ormond Stone. [4]

Due to its high rate of star formation NGC 178 is a starburst galaxy. [4] It is forming new stars at a rate of 0.55 M☉ per year. [3] The peculiar morphology of this galaxy may be a sign of it being a galaxy merger. [6]
