UGPS J072227.51−054031.2 (designation often abbreviated to UGPS 0722−05) is a sub-brown dwarf or rogue planet of late T type, located approximately from Earth.
The object is roughly the volume of Jupiter, but is estimated to have 3–11 Jupiter masses (MJ). This would make it less massive than ε Indi Ba. Planets have a mass of less than about 13 Jupiter masses. Infrared spectra shows the object contains water vapor and methane and has a surface temperature of approximately 480–560 kelvins.
History of observations.
UGPS 0722-05 was discovered by Philip Lucas at the University of Hertfordshire and announced in 2010. The discovery image was taken on 28 November 2006 by the UKIRT Infrared Deep Sky Survey (UKIDSS) with a recovery image confirming the object's proper motion on 2 March 2010. 
It was initially reported to be at an even closer distance of , which would have placed it among the ten nearest astronomical objects to the Sun, but later measurements revealed that the object was in fact located at a greater distance than initially thought, at ().
Space motion.
UGPS 0722−05 has proper motion of about 970 milliarcseconds per year.
Radial velocity of UGPS 0722-05, measured by Bochanski "et al." and published in 2011, is .
