Ses planètes
HD 3167 b — 1.6 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 23 hours; about 1,500 °C, hot enough to melt rock; found in 2016 by transit.
HD 3167 c — 3 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 30 days; about 290 °C, hotter than boiling water; found in 2016 by transit.
HD 3167 d — 2.6 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 8 days; about 590 °C, hotter than boiling water; found in 2017 by radial velocity.
HD 3167 e — 4 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 92 days; about 120 °C, hotter than boiling water; found in 2022 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.
