NGC 17 = NGC 34 is an active spiral galaxy with extended star formation from the Hubble type S / P in the constellation Cetus south of the ecliptic . It is estimated to be 265 million light years from the Milky Way and about 165,000 light years in diameter . The galaxy is in the final stages of merging two galaxies.

The object was discovered in 1886 by the American astronomer Frank Muller . On November 21, 1886, Lewis A. Swift observed the same galaxy; Since it was initially not recognized that the observations were on the same object, the galaxy at times had two catalog numbers, NGC 17 and NGC 34 .
