DEN 1048−3956

DEN 1048−3956 is a brown dwarf about 13 light years from Earth in the southern constellation of Antlia, among the closest interstellar objects to Earth. This substellar object is very dim with an apparent magnitude of about 17, and will require 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 (Canada–France–Hawaii Telescope Corporation), with the assistance of nine other astronomers.

In 2005 a powerful flare from this object was detected by radio astronomy.
