Kepler-37 d — 2 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 40 days; about 230 °C, hotter than boiling water; found in 2013 by transit.
Kepler-37 b — 0.3 times Earth's width, smaller than the Earth; its year lasts 13 days; about 450 °C, hotter than boiling water; found in 2013 by transit.
Kepler-37 c — 0.8 times Earth's width, smaller than the Earth; its year lasts 21 days; about 340 °C, hotter than boiling water; found in 2013 by transit.
Kepler-37 e — 0.4 times Earth's width, smaller than the Earth; its year lasts 51 days; about 130 °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.
