Come è stato scoperto
Primo pianeta scoperto nel 2002 con la velocità radiale (NASA Exoplanet Archive).
I suoi pianeti
HD 8574 b — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 230 days; about 120 °C, hotter than boiling water; found in 2002 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.
