Gliese 758 B (often shortened to GJ 758 B) is a brown dwarf orbiting the G-type main sequence star Gliese 758, located approximately 50 light years away, in the constellation Lyra.
Gliese 758 B was detected by direct imaging using the HiCIAO instrument of the Subaru Telescope.[3][4][5] The parameters have subsequently been revised in a follow-up study which also revealed that a putative second substellar object in the system was in fact an unrelated background star.[6]
