Estrela com 2 planetas conhecidos

Pr0211

Pr0211 tem 2 planetas confirmados.

Medido

Sobre 596 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 2012 por velocidade radial (NASA Exoplanet Archive).

Pr0211 b — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 2 days; about 1,000 °C, hot enough to melt rock; found in 2012 by radial velocity.
Pr0211 c — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 13 Earth years; about −170 °C, below freezing; found in 2016 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.
