NGC 1134 is a spiral galaxy of Hubble type Sb with extensive star formation in the constellation Aries at the northern sky . It is an estimated 164 million light years from the Milky Way and about 120,000 light years in diameter. Together with IC 267 it forms a probably gravitationally bound galaxy pair .
In the same area of the sky are u. a. the galaxies NGC 1115 , NGC 1116 , NGC 1117 , NGC 1127 .
Halton Arp organized his catalog of unusual galaxies into groups according to purely morphological criteria. This galaxy belongs to the class of galaxies with matter ejected from the nucleus .
The object was discovered by Wilhelm Herschel on October 16, 1784 .
