G 261-6 b has an equilibrium temperature between −50 and +50 °C.
How it was found
First planet found in 2025, by radial velocity (NASA Exoplanet Archive).
Its planets
G 261-6 b — 1.1 times Earth's width (estimated from its mass, not measured), about Earth-sized — probably rocky; its year lasts 5 days; about 49 °C, between freezing and boiling; found in 2025 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.
