NGC 151 = NGC 153 is a bar-spiral galaxy with an active nucleus of the Hubble type SBbc in the constellation Whale south of the celestial equator . It is an estimated 170 million light-years from the Milky Way and about 125,000 light-years across. Together with NGC 217 , PGC 1841 and PGC 1909 it forms the NGC 151 group .
The galaxies NGC 163 and NGC 165 are located in the same area of ​​the sky .

The Type IIn supernova iPTF 13iqb was observed here.

The object was discovered on November 28, 1785 by the German-British astronomer Wilhelm Herschel . The American astronomer Lewis A. Swift observed the same galaxy on August 9, 1886. However, the double observation was not recognized and therefore it was given the number NGC 153 .
