Estrella con 2 planetas conocidos

K2-154

K2-154, una estrella M0.0 V, tiene 2 planetas confirmados.

Medido

Acerca de 422 años luz. Para cruzarlo:

La Voyager 1 a la velocidad con la que se alejó durante el año hasta 2026-10-25 (JPL Horizons). Conduciendo: sin parar, sin repostar nunca.

K2-154 c — 2.1 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 8 days; about 280 °C, hotter than boiling water; found in 2018 by transit.
K2-154 b — 2 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 4 days; about 440 °C, hotter than boiling water; found in 2018 by transit.

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.
