Stella con 3 pianeti noti

HD 73344

HD 73344, una stella F6 V, ha 3 pianeti confermati.

Misurato

Informazioni 115 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 2024 con la velocità radiale e il transito (NASA Exoplanet Archive).

HD 73344 c — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 66 days; about 290 °C, hotter than boiling water; found in 2025 by radial velocity.
HD 73344 b — 2.9 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 16 days; about 640 °C, hotter than boiling water; found in 2024 by transit.
HD 73344 d — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 16 Earth years; about −150 °C, below freezing; found in 2025 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.
