Facts
HIP 8541 b has an equilibrium temperature between −50 and +50 °C.
How it was found
First planet found in 2016, by radial velocity (NASA Exoplanet Archive).
Its planets
HD 11343 c — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 230 days; about 340 °C, hotter than boiling water; found in 2022 by radial velocity.
HIP 8541 b — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 5 Earth years; about 32 °C, between freezing and boiling; found in 2016 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.
