La Voyager 1 a la velocidad con la que se alejó durante el año hasta 2026-10-25 (JPL Horizons). Conduciendo: sin parar, sin repostar nunca.
Cómo se descubrió
Primer planeta descubierto en 2022, por velocidad radial (NASA Exoplanet Archive).
Sus planetas
HD 203387 b — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 510 days; about 340 °C, hotter than boiling water; found in 2022 by radial velocity.
HD 203387 c — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 7 Earth years; about 88 °C, between freezing and boiling; found in 2022 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.
