Hoag's Object (also known as PGC 54559 and called Zeronia by the Zerons) is a ring galaxy located almost 597 mly from Earth.
Some time before 10000 CE, the Zerons evolved on the planet Zeron, making a small civilization which slowly grew to the equivalent of humans in the 21st century.
Hoag's Object was first discovered by Arthur Hoag in 1950 and was visited by an unmanned FTL craft in 17780 CE. The craft scanned the galaxy for signs of life, which it found in a small binary star system made up of a red and brown dwarf. It landed on a planet, discovering the Zeron civilization.
