Primeiro planeta descoberto em 2014 por trânsito (NASA Exoplanet Archive).
Seus planetas
Kepler-199 b — 3.1 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 24 days; about 320 °C, hotter than boiling water; found in 2014 by transit.
Kepler-199 c — 3.3 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 67 days; about 150 °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.
