Estrella con 2 planetas conocidos

HD 83443

HD 83443, una estrella K0 V, tiene 2 planetas confirmados.

Medido

Acerca de 133 años luz. Para cruzarlo:

La Voyager 1 a la velocidad con la que se alejó durante el año hasta 2026-10-25 (JPL Horizons). Conduciendo: sin parar, sin repostar nunca.

Primer planeta descubierto en 2002, por velocidad radial (NASA Exoplanet Archive).

HD 83443 b — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 3 days; about 990 °C, hotter than boiling water; found in 2002 by radial velocity.
HD 83443 c — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 23 Earth years; about −180 °C, below freezing; found in 2022 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.
