Hen 2-10, also known as He 2-10 and Henize 2-10, is a dwarf starburst galaxy located 34 million light years away in the constellation of Pyxis.
Supporting evidence for the reclassification came in the form of excess infrared emission and a higher than usual density of neutral hydrogen.
This tidal tail suggests that Hen 2-10 may have had past interactions with other galaxies, possibly even a merger event.
