Stella con 3 pianeti noti

GJ 367

GJ 367, una stella M1.0 V, ha 3 pianeti confermati.

Misurato

Informazioni 30.7 anni luce. Per attraversarlo:

Voyager 1 alla velocità con cui si è allontanata nell'anno fino al 2026-10-25 (JPL Horizons). In auto: senza sosta, senza mai fare rifornimento.

Primo pianeta scoperto nel 2021 con il transito e la velocità radiale (NASA Exoplanet Archive).

GJ 367 b — 0.7 times Earth's width, smaller than the Earth; its year lasts 8 hours; about 1,100 °C, hot enough to melt rock; found in 2021 by transit.
GJ 367 c — 1.9 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 12 days; found in 2023 by radial velocity.
GJ 367 d — 2.3 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 34 days; found in 2023 by radial velocity.

NASA Exoplanet Archive, Planetary Systems Composite Parameters (fetched 2026-11-02). Composite values: where a planet's size or mass was not measured, the archive estimates it from the other.
This research has made use of the NASA Exoplanet Archive, which is operated by the California Institute of Technology, under contract with NASA under the Exoplanet Exploration Program.
