Cómo se descubrió

Primer planeta descubierto en 1996, por velocidad radial (NASA Exoplanet Archive).

Sus planetas

47 UMa b — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 3 Earth years; about −58 °C, below freezing; found in 1996 by radial velocity.
47 UMa c — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 7 Earth years; about −110 °C, below freezing; found in 2001 by radial velocity.
47 UMa d — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 38 Earth years; about −180 °C, below freezing; found in 2009 by radial velocity.

De dónde proceden estos datos

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.
