Voyager 1 à velocidade com que se afastou ao longo do ano até 2026-10-25 (JPL Horizons). Dirigindo: sem parar, sem nunca reabastecer.
Como foi descoberto
Primeiro planeta descoberto em 2018 por velocidade radial e trânsito (NASA Exoplanet Archive).
Seus planetas
Kepler-1656 c — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 5 Earth years; about −110 °C, below freezing; found in 2022 by radial velocity.
Kepler-1656 b — 4.6 times Earth's width, Neptune-sized; its year lasts 32 days; about 380 °C, hotter than boiling water; found in 2018 by transit.
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.
