Kepler-48 f — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 14 Earth years; about −180 °C, below freezing; found in 2023 by radial velocity.
Kepler-48 b — 1.9 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 5 days; about 660 °C, hotter than boiling water; found in 2012 by transit.
Kepler-48 e — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 3 Earth years; about −100 °C, below freezing; found in 2014 by radial velocity.
Kepler-48 c — 2.7 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 10 days; about 460 °C, hotter than boiling water; found in 2012 by transit.
Kepler-48 d — 2 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 43 days; about 180 °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.
