Estrela com 2 planetas conhecidos

7 CMa

7 CMa, uma estrela K1III(+M), tem 2 planetas confirmados.

Medido

Sobre 64.6 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 2011 por velocidade radial (NASA Exoplanet Archive).

7 CMa 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 110 °C, hotter than boiling water; found in 2011 by radial velocity.
7 CMa 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 77 °C, between freezing and boiling; found in 2019 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.
