NGC 5078 is a spiral galaxy in the Hydra constellation, approximately 94 million light-years away from Earth.[2] It has a diameter of 127,000 light-years and is probably a member of the NGC 5061 group.[3] The dust lane of NGC 5078 is warped, probably by interaction with the nearby galaxy IC 879, which is itself distorted into an 'S' shape by the interaction.[4] At the presumed distance the two galaxies would have a minimal separation of about 61,000 light-years.[3] For comparison, the Large Magellanic Cloud is about 160,000 light-years from the Milky Way.

NGC 5078 is also only separated in the sky from the spiral galaxy NGC 5101 by about 0.5 degrees, and both are believed to be at the same distance from the Earth. This would mean they are approximately 800,000 light-years apart.[5]

One supernova has been observed in NGC 5078: SN 1999cz (type Ic, mag. 16).[6]
