Estrela com 2 planetas conhecidos

nu Oph

nu Oph, uma estrela K0 III, tem 2 planetas confirmados.

Medido

Sobre 151 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).

nu Oph b — 12 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 530 days; about 350 °C, hotter than boiling water; found in 2012 by radial velocity.
nu Oph c — 12 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 9 Earth years; about 68 °C, between freezing and boiling; found in 2012 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.
