Sus planetas
HD 159243 c — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 250 days; about 76 °C, between freezing and boiling; found in 2013 by radial velocity.
HD 159243 b — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 13 days; about 670 °C, hotter than boiling water; found in 2013 by radial velocity.
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.
