Sus planetas

HD 48948 c — 2.6 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 38 days; about 280 °C, hotter than boiling water; found in 2024 by radial velocity.
HD 48948 b — 2.1 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 7 days; about 680 °C, hotter than boiling water; found in 2024 by radial velocity.
HD 48948 d — 3.2 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 150 days; about 76 °C, between freezing and boiling; found in 2024 by radial velocity.

De dónde proceden estos datos

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.
