Estrela com 2 planetas conhecidos

Kepler-87

Kepler-87 tem 2 planetas confirmados.

Medido

Sobre 4,020 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-87 b — 13 times Earth's width, a giant, Jupiter-sized or more; its year lasts 110 days; about 210 °C, hotter than boiling water; found in 2013 by transit.
Kepler-87 c — 6.1 times Earth's width, Neptune-sized; its year lasts 190 days; about 130 °C, hotter than boiling water; found in 2013 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.
