Stella con 3 pianeti noti

HD 7924

HD 7924, una stella K0.5 V, ha 3 pianeti confermati.

Misurato

Informazioni 55.4 anni luce. Per attraversarlo:

Voyager 1 alla velocità con cui si è allontanata nell'anno fino al 2026-10-25 (JPL Horizons). In auto: senza sosta, senza mai fare rifornimento.

Primo pianeta scoperto nel 2008 con la velocità radiale (NASA Exoplanet Archive).

HD 7924 b — about 2,100 times Earth's mass; its year lasts 5 days; about 550 °C, hotter than boiling water; found in 2008 by radial velocity.
HD 7924 d — about 1,600 times Earth's mass; its year lasts 24 days; about 230 °C, hotter than boiling water; found in 2015 by radial velocity.
HD 7924 c — about 1,800 times Earth's mass; its year lasts 15 days; about 310 °C, hotter than boiling water; 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.
