Kepler-164 e — 4.2 times Earth's width, Neptune-sized; its year lasts 95 days; about 160 °C, hotter than boiling water; found in 2023 by transit.
Kepler-164 d — 2.5 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 29 days; about 360 °C, hotter than boiling water; found in 2014 by transit.
Kepler-164 b — 1.4 times Earth's width, about Earth-sized — probably rocky; its year lasts 5 days; about 870 °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.
