Stella con 2 pianeti noti

HD 107148

HD 107148, una stella G5 V, ha 2 pianeti confermati.

Misurato

Informazioni 161 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 2005 con la velocità radiale (NASA Exoplanet Archive).

HD 107148 b — 9.6 times Earth's width (estimated from its mass, not measured), Neptune-sized; its year lasts 48 days; about 310 °C, hotter than boiling water; found in 2005 by radial velocity.
HD 107148 c — 4.7 times Earth's width (estimated from its mass, not measured), Neptune-sized; its year lasts 18 days; about 530 °C, hotter than boiling water; found in 2021 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.
