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.
Cómo se descubrió
Primer planeta descubierto en 2014, por tránsito (NASA Exoplanet Archive).
Sus planetas
Kepler-342 b — 2.3 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 15 days; about 630 °C, hotter than boiling water; found in 2014 by transit.
Kepler-342 e — 0.9 times Earth's width, about Earth-sized — probably rocky; its year lasts 39 hours; about 1,600 °C, hot enough to melt rock; found in 2016 by transit.
Kepler-342 d — 2.5 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 39 days; about 390 °C, hotter than boiling water; found in 2014 by transit.
Kepler-342 c — 2 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 26 days; about 480 °C, hotter than boiling water; found in 2014 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.
