SN 2005gj was a supernova located approximately 864 million light years (265 million parsecs) away from Earth. It was discovered on September 27, 2005, by the Sloan Digital Sky Survey and the Nearby Supernova Factory.{{cite web |url=http://sdssdp47.fnal.gov/sdsssn/talks/AAS-1-07/aas07_prieto.pdf |title=Peculiar Supernovae in SDSS-II |author=J.

2005gj was also noted for its overluminosity. With a light curve that maximised 14–47 days after the initial observation, it was three times more luminous than SN 1991T (which was, at the time of its 1991 discovery, the brightest Ia supernova on record), 1.5 times more luminous than SN 2002ic, and close to 100 times more luminous than previously thought possible. |title=The extravagant universe |author=R.
