Estrela com 2 planetas conhecidos

HD 48265

HD 48265, uma estrela G5 IV/V, tem 2 planetas confirmados.

Medido

Sobre 295 anos-luz. Para atravessá-lo:

Voyager 1 à velocidade com que se afastou ao longo do ano até 2026-10-25 (JPL Horizons). Dirigindo: sem parar, sem nunca reabastecer.

Primeiro planeta descoberto em 2008 por velocidade radial (NASA Exoplanet Archive).

HD 48265 c — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 29 Earth years; about −150 °C, below freezing; found in 2026 by radial velocity.
HD 48265 b — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 2 Earth years; about 10 °C, between freezing and boiling; found in 2008 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.
