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 1061 - System
GJ 1061, a cool M-dwarf of 0.12 solar masses, and GJ 1061 b, a 1.1-Earth-mass planet, with an orbital period of 3.2 days, at 0.021 AU from its star.
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 1151 - System
GJ 1151, a cool M-dwarf of 0.16 solar masses, and GJ 1151 c, a 10.6-Earth-mass planet, with an orbital period of 1.07 years, at 0.571 AU from its star.
GJ 1214 - System
GJ 1214 b, the archetype sub-Neptune. This nearby mini-Neptune has a famously flat transmission spectrum, hiding water, haze, or both. The red-dwarf host is only about 48 light-years away.
GJ 1252 - System
GJ 1252, a cool M-dwarf of 0.38 solar masses, and GJ 1252 b, a 1.3-Earth-mass planet, with an orbital period of 12.4 hours.
GJ 1265 - System
GJ 1265, a cool M-dwarf of 0.18 solar masses, and GJ 1265 b, a 7.4-Earth-mass planet, with an orbital period of 3.7 days, at 0.026 AU from its star.
GJ 1289 - System
GJ 1289, a cool M-dwarf of 0.21 solar masses, and GJ 1289 b, a 6.3-Earth-mass planet, with an orbital period of 112 days, at 0.270 AU from its star, and an equilibrium temperature near 150 K.
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 160.2 - System
GJ 160.2, a cool M-dwarf of 0.69 solar masses, and GJ 160.2 b, a 10.2-Earth-mass planet, with an orbital period of 5.2 days, at 0.053 AU from its star, on an eccentric orbit (e ≈ 0.06).
GJ 163 - System
GJ 163, a cool M-dwarf of 0.40 solar masses, and GJ 163 b, a 10.6-Earth-mass planet, with an orbital period of 8.6 days, at 0.061 AU from its star, on an eccentric orbit (e ≈ 0.07).
GJ 179 - System
GJ 179, a cool M-dwarf of 0.36 solar masses, and GJ 179 b, a 0.82-Jupiter-mass companion, with an orbital period of 6.26 years, at 2.410 AU from its star, on an eccentric orbit (e ≈ 0.21).
GJ 180 - System
GJ 180, a cool M-dwarf of 0.43 solar masses, and GJ 180 b, a 6.5-Earth-mass planet, with an orbital period of 17.1 days, at 0.092 AU from its star, on an eccentric orbit (e ≈ 0.07).
