Gliese 758 B [SEP] constellation
Gliese 758 B
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. 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.

Gliese 758 B orbits
In November 2009, a team using the HiCIAO instrument of the Subaru Telescope imaged a substellar companion orbiting the star. This object, designated Gliese 758 B, was estimated to be of approximately 10-40 Jupiter masses. A second candidate object was also detected, which was given the designation Gliese 758 C. Follow-up studies of the system suggested the mass range of Gliese 758 b, indicating it to be a companion with approximately 30 to 40 Jupiter masses and revealed that Gliese 758 C is a background star which is not
