Estrela com 2 planetas conhecidos

WASP-8

WASP-8, uma estrela G8 V, tem 2 planetas confirmados.

Medido

Sobre 293 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 2010 por trânsito e velocidade radial (NASA Exoplanet Archive).

WASP-8 b — 13 times Earth's width, a giant, Jupiter-sized or more; its year lasts 8 days; about 790 °C, hotter than boiling water; found in 2010 by transit.
WASP-8 c — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 12 Earth years; about −160 °C, below freezing; found in 2013 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.
