Estrela com 2 planetas conhecidos

WISPIT 1

WISPIT 1, uma estrela K4 V, tem 2 planetas confirmados.

Medido

Sobre 750 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.

WISPIT 1 b — 12 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; about −260 °C, below freezing; found in 2025 by imaging.
WISPIT 1 c — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; about −270 °C, below freezing; found in 2025 by imaging.

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.
