K2-381

K2-381 tiene 3 planetas confirmados.

Medido

Acerca de 475 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.

K2-381 c — 2 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 16 days; found in 2022 by transit.
K2-381 d — 1.7 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 27 days; found in 2022 by transit.
K2-381 b — 1.1 times Earth's width, about Earth-sized — probably rocky; its year lasts 8 days; found in 2022 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.
