Estrela com 3 planetas conhecidos

GJ 367

GJ 367, uma estrela M1.0 V, tem 3 planetas confirmados.

Medido

Sobre 30.7 anos-luz. Para atravessá-lo:

Voyager 1 à velocidade com que se afastou ao longo do ano até 2026-10-25 (JPL Horizons). Dirigindo: sem parar, sem nunca reabastecer.

Primeiro planeta descoberto em 2021 por trânsito e velocidade radial (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.
