Estrela com 2 planetas conhecidos

Kepler-879

Kepler-879, uma estrela G, tem 2 planetas confirmados.

Medido

Sobre 2,620 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-879 c — 0.4 times Earth's width, smaller than the Earth; its year lasts 16 hours; found in 2024 by transit.
Kepler-879 b — 2.6 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 33 days; about 310 °C, hotter than boiling water; found in 2016 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.
