Seus planetas
Kepler-297 b — 2.9 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 39 days; about 240 °C, hotter than boiling water; found in 2014 by transit.
Kepler-297 c — 6.5 times Earth's width, Neptune-sized; its year lasts 75 days; about 140 °C, hotter than boiling water; found in 2014 by transit.
Kepler-297 d — 7.1 times Earth's width, Neptune-sized; its year lasts 150 days; about 52 °C, between freezing and boiling; found in 2023 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.
