NGC 3312 is a large[3] and highly inclined[4] spiral galaxy[5] located about 194 million light-years away[6] in the constellation Hydra.

NGC 3312 was later listed and equated with IC 629 because the two objects share essentially the same celestial coordinates.

This may have caused the filamentary extensions observed in NGC 3312 as evidenced by the location of the galaxy near the cluster core.

Although NGC 3312's morphological structure resembles that of anemic galaxies, its mean surface-brightness profile hints that star formation may be quite active.

The northwest filamentary extension from NGC 3312 has high surface brightness and has the knotted texture characteristic of active star-forming regions in spiral arms.
