GJ 3512 - System
GJ 3512, a cool M-dwarf of 0.12 solar masses, and GJ 3512 b, a 0.46-Jupiter-mass companion, with an orbital period of 203 days, at 0.338 AU from its star, on an eccentric orbit (e ≈ 0.43).
GJ 357 - System
GJ 357, a nearby red dwarf with a transiting hot Earth and an outer habitable-zone planet. The outer world does not transit. The system is about 31 light-years from the Sun.
GJ 3634 - System
GJ 3634, a cool M-dwarf of 0.45 solar masses, and GJ 3634 b, a 8.4-Earth-mass planet, with an orbital period of 2.6 days, at 0.029 AU from its star, on an eccentric orbit (e ≈ 0.08).
GJ 367 - System
GJ 367 b, an iron-rich world on an ultra-short orbit. A year lasts about eight hours, and the high density points to an exposed iron core. The density is higher than Earth's.
GJ 3779 - System
GJ 3779, a cool M-dwarf of 0.27 solar masses, and GJ 3779 b, a 8.0-Earth-mass planet, with an orbital period of 3.0 days, at 0.026 AU from its star, on an eccentric orbit (e ≈ 0.07).
GJ 3929 - System
GJ 3929, a cool M-dwarf of 0.31 solar masses, and GJ 3929 b, a 1.8-Earth-mass planet, with an orbital period of 2.6 days, at 0.025 AU from its star, and an equilibrium temperature near 568 K.
GJ 393 - System
