Stella con 2 pianeti noti

HD 72659

HD 72659, una stella G2 V, ha 2 pianeti confermati.

Misurato

Informazioni 169 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 2002 con la velocità radiale (NASA Exoplanet Archive).

HD 72659 b — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 10 Earth years; about −120 °C, below freezing; found in 2002 by radial velocity.
HD 72659 c — 12 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 97 Earth years; about −200 °C, below freezing; 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.
