NGC 5078
Template:Short description Template:Infobox Galaxy
NGC 5078 is a spiral galaxy in the Hydra constellation, approximately 94 million light-years away from Earth.<ref name=AOP /> It has a diameter of 127,000 light-years.<ref name=Bratton>Template:Cite book</ref> It was discoverd by German-British astronomer William Herschel on 28 March 1786.<ref>Template:Cite journal</ref><ref name="selig">Template:Cite web</ref>
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.<ref name=AAO>Template:Cite web</ref> At the presumed distance the two galaxies would have a minimal separation of about 61,000 light-years.<ref name=Bratton /> 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.<ref name="APOD">Template:Cite web</ref>
