Datos

HD 69830 d tiene una temperatura de equilibrio de entre −50 y +50 °C.

Cómo se descubrió

Primer planeta descubierto en 2006, por velocidad radial (NASA Exoplanet Archive).

Sus planetas

HD 69830 b — 3.2 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 9 days; about 600 °C, hotter than boiling water; found in 2006 by radial velocity.
HD 69830 d — 4.5 times Earth's width (estimated from its mass, not measured), Neptune-sized; its year lasts 200 days; about 35 °C, between freezing and boiling; found in 2006 by radial velocity.
HD 69830 c — 3.5 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 32 days; about 290 °C, hotter than boiling water; found in 2006 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.
