Estrela com 2 planetas conhecidos

Kepler-1649

Kepler-1649 tem 2 planetas confirmados.

Medido

Sobre 301 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.

Kepler-1649 c e Kepler-1649 b têm uma temperatura de equilíbrio entre −50 e +50 °C.

Kepler-1649 c — 1.1 times Earth's width, about Earth-sized — probably rocky; its year lasts 20 days; about −39 °C, below freezing; found in 2020 by transit.
Kepler-1649 b — 1 times Earth's width, about Earth-sized — probably rocky; its year lasts 9 days; about 34 °C, between freezing and boiling; found in 2017 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.
