Come è stato scoperto

Primo pianeta scoperto nel 2014 con il transito (NASA Exoplanet Archive).

I suoi pianeti

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.

Da dove proviene

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.

Ogni catalogo utilizzato da Ouranos è citato nella pagina dei crediti.
