Facts
HIP 67851 c has an equilibrium temperature between −50 and +50 °C.
How it was found
First planet found in 2015, by radial velocity (NASA Exoplanet Archive).
Its planets
HIP 67851 b — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 89 days; about 570 °C, hotter than boiling water; found in 2015 by radial velocity.
HIP 67851 c — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 9 Earth years; about −18 °C, below freezing; found in 2015 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.
