Stella con 2 pianeti noti

HD 1461

HD 1461, una stella G0 V, ha 2 pianeti confermati.

Misurato

Informazioni 76.5 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 2010 con la velocità radiale (NASA Exoplanet Archive).

HD 1461 b — 2.4 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 6 days; about 910 °C, hotter than boiling water; found in 2010 by radial velocity.
HD 1461 c — 2.2 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 620 °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.
