Gliese 3021 b [SEP] constellation
Gliese 3021 b
Gliese 3021 b, also known as GJ 3021 b or HD 1237 b, is an extrasolar planet approximately 57 light-years away, orbiting its bright G-dwarf parent star in the Southern constellation of Hydrus. It was discovered with the Swiss Euler Telescope at the Chilean La Silla Observatory in 2000.
As determined by doppler spectroscopy, the jovian planet has an elongated orbit about 0.5 AU from its host star and a minimum mass 3.37 times that of Jupiter. Its orbital period of more than 133
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.
