Stella con 4 pianeti noti

HD 215152

HD 215152, una stella K3 V, ha 4 pianeti confermati.

Misurato

Informazioni 70.4 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 2018 con la velocità radiale (NASA Exoplanet Archive).

HD 215152 b — about 570 times Earth's mass; its year lasts 6 days; about 570 °C, hotter than boiling water; found in 2018 by radial velocity.
HD 215152 c — about 470 times Earth's mass; its year lasts 7 days; about 510 °C, hotter than boiling water; found in 2018 by radial velocity.
HD 215152 d — about 770 times Earth's mass; its year lasts 11 days; about 410 °C, hotter than boiling water; found in 2018 by radial velocity.
HD 215152 e — about 980 times Earth's mass; its year lasts 25 days; about 250 °C, hotter than boiling water; found in 2018 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.
