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.^[7]^[8] 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.^[9]

Orbit

Gliese 758 B orbits its host star in an eccentric orbit with a semimajor axis of {{val|21.1|2.7|1.3}} Astronomical units and an orbital period of {{val|96|21|9}} years, which takes it within 9 astronomical units at its closest approach.^[10]
