DENIS J1048âÂÂ3956 is an exceptionally small, dim ultra-cool red dwarf star from Earth in the southern constellation of Antlia, among the stars closest to Earth. This star is very dim with an apparent magnitude of about 17, and requires a telescope with a camera to be seen. It was discovered in 2000 by Xavier Delfosse (Institute of Astrophysics of the Canary Islands, now Observatoire de Grenoble) and Thierry Forveille (CanadaâÂÂFranceâÂÂHawaii Telescope Corporation), with the assistance of nine other astronomers.
Kinematically, DENIS J1048âÂÂ3956 belongs to the young thin disc. In 2005 a powerful flare from this object was detected by radio astronomy.
