Datos

Kepler-445 d tiene una temperatura de equilibrio de entre −50 y +50 °C.

Cómo se descubrió

Primer planeta descubierto en 2015, por tránsito (NASA Exoplanet Archive).

Sus planetas

Kepler-445 b — 1.6 times Earth's width, about Earth-sized — probably rocky; its year lasts 3 days; about 130 °C, hotter than boiling water; found in 2015 by transit.
Kepler-445 c — 2.5 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 5 days; about 68 °C, between freezing and boiling; found in 2015 by transit.
Kepler-445 d — 1.3 times Earth's width, about Earth-sized — probably rocky; its year lasts 8 days; about 32 °C, between freezing and boiling; found in 2015 by transit.

De dónde proceden estos datos

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.
