Stella con 2 pianeti noti

HD 33844

HD 33844, una stella K0 III, ha 2 pianeti confermati.

Misurato

Informazioni 345 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 2015 con la velocità radiale (NASA Exoplanet Archive).

HD 33844 c — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 3 Earth years; about 87 °C, between freezing and boiling; found in 2015 by radial velocity.
HD 33844 b — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 550 days; about 160 °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.
