Voyager 1 à la vitesse à laquelle elle s'est éloignée au cours de l'année jusqu'à 2026-10-25 (JPL Horizons). En voiture : sans arrêt, sans jamais refaire le plein.
Méthode de découverte
Première planète découverte en 2012, par transit et vitesse radiale (NASA Exoplanet Archive).
Ses planètes
Kepler-65 d — 1.5 times Earth's width, about Earth-sized — probably rocky; its year lasts 8 days; about 840 °C, hotter than boiling water; found in 2012 by transit.
Kepler-65 c — 2.6 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 6 days; about 970 °C, hotter than boiling water; found in 2012 by transit.
Kepler-65 b — 1.4 times Earth's width, about Earth-sized — probably rocky; its year lasts 2 days; about 1,500 °C, hot enough to melt rock; found in 2012 by transit.
Kepler-65 e — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 260 days; about 120 °C, hotter than boiling water; found in 2019 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.
