Facts
HIP 107772 b has an equilibrium temperature between −50 and +50 °C.
How it was found
First planet found in 2020, by radial velocity (NASA Exoplanet Archive).
Its planets
HIP 107772 b — 3.6 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 55 days; about 8 °C, between freezing and boiling; found in 2020 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.
