Estrella con 2 planetas conocidos

7 CMa

7 CMa, una estrella K1III(+M), tiene 2 planetas confirmados.

Medido

Acerca de 64.6 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 2011, por velocidad 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.
