IC 128 is a faint bar spiral galaxy of the Hubble type SBc in the constellation Whale south of the ecliptic . It is around 236 million light years away from the Milky Way and has a diameter of around 65,000 light years . The galaxy is likely interacting with IC 129 , which explains both its expanded spiral arms and the tidal tail .
In the same area of the sky are u. a. the galaxies NGC 593 , NGC 599 , IC 129 , IC 1714 .
The object was discovered by Stéphane Javelle on January 3, 1891 .
