K2-233 d — 2.4 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 24 days; about 250 °C, hotter than boiling water; found in 2018 by transit.
K2-233 c — 1.3 times Earth's width, about Earth-sized — probably rocky; its year lasts 7 days; about 520 °C, hotter than boiling water; found in 2018 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.
