NGC 144 is a spiral galaxy of Hubble type Sc with vast star-forming regions in the constellation Cetus south of the ecliptic . It is estimated to be 365 million light years from the Milky Way and about 85,000 light years in diameter. Presumably, it forms a gravitationally bound galaxy trio together with NGC 142 and NGC 143 .
The object was discovered in 1886 by the American astronomer Frank Muller .
