Estrela com 3 planetas conhecidos

Kepler-25

Kepler-25, uma estrela F8, tem 3 planetas confirmados.

Medido

Sobre 793 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.

Primeiro planeta descoberto em 2011 por trânsito e velocidade radial (NASA Exoplanet Archive).

Kepler-25 b — 2.8 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 6 days; about 910 °C, hotter than boiling water; found in 2011 by transit.
Kepler-25 c — 5.2 times Earth's width, Neptune-sized; its year lasts 13 days; about 660 °C, hotter than boiling water; found in 2011 by transit.
Kepler-25 d — 10 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 120 days; about 270 °C, hotter than boiling water; found in 2014 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.
