G 264-012 - System
G 264-012, a cool M-dwarf of 0.30 solar masses, and G 264-012 b, a 2.5-Earth-mass planet, with an orbital period of 2.3 days, at 0.023 AU from its star, and an equilibrium temperature near 587 K.
GJ 1002 - System
GJ 1002, a nearby quiet red dwarf with two Earth-mass planets in the habitable zone, among the closest temperate worlds known. Both planets were found by radial-velocity monitoring.
GJ 1132 - System
GJ 1132 b, a nearby rocky planet that may have lost and then rebuilt an atmosphere. It is a key JWST target for secondary atmospheres. The red dwarf is only about 41 light-years from the Sun.
GJ 1148 - System
GJ 1148, a cool M-dwarf of 0.34 solar masses, and GJ 1148 b, a 0.30-Jupiter-mass companion, with an orbital period of 41.4 days, at 0.166 AU from its star, on an eccentric orbit (e ≈ 0.38).
GJ 143 - System
GJ 143, an orange K-type dwarf of 0.73 solar masses, and HD 21749 c, a 3.7-Earth-mass planet, with an orbital period of 7.8 days, at 0.070 AU from its star, and an equilibrium temperature near 701 K.
GJ 15 A - System
GJ 15 A, a cool M-dwarf of 0.38 solar masses, and GJ 15 A b, a 3.0-Earth-mass planet, with an orbital period of 11.4 days, at 0.072 AU from its star, on an eccentric orbit (e ≈ 0.09).
GJ 2030 - System
