Stella con 3 pianeti noti

K2-239

K2-239, una stella M3.0 V, ha 3 pianeti confermati.

Misurato

Informazioni 101 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.

K2-239 d — 1.1 times Earth's width, about Earth-sized — probably rocky; its year lasts 10 days; about 130 °C, hotter than boiling water; found in 2018 by transit.
K2-239 c — 1 times Earth's width, about Earth-sized — probably rocky; its year lasts 8 days; about 150 °C, hotter than boiling water; found in 2018 by transit.
K2-239 b — 1.1 times Earth's width, about Earth-sized — probably rocky; its year lasts 5 days; about 230 °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.
