NGC 3647
NGC 3647 is a small elliptical galaxy in the Leo constellation.[1] The galaxy was first discovered on March 22, 1865 by Albert Marth who was a German astronomer.[2] It is approximately 747 million light-years away.[3] Due to its close proximity to five other elliptical galaxies, there was a bit of confusion for Marth to identify which object is NGC 3647.[2] According to SIMBAD, it is identified as PGC 34816.[4] But in HyperLeda and by NASA/IPAC databases, NGC 3647 is identified as PGC 34815.[3] The correct designation for this article, according sources from wikidata is PGC 34816. There is no evidence whether this galaxy has an active nucleus or not. References
