Stella con 2 pianeti noti

HD 51608

HD 51608, una stella G7 V, ha 2 pianeti confermati.

Misurato

Informazioni 114 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 2019 con la velocità radiale (NASA Exoplanet Archive).

HD 51608 b — 3.6 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 14 days; about 490 °C, hotter than boiling water; found in 2019 by radial velocity.
HD 51608 c — 3.9 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 96 days; about 130 °C, hotter than boiling water; found in 2019 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.
