Wie er entdeckt wurde

Erster Planet, entdeckt 2024 durch Radialgeschwindigkeit und Transit (NASA Exoplanet Archive).

Seine Planeten

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.

Woher das stammt

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.
