Estrella con 3 planetas conocidos

Kepler-46

Kepler-46, una estrella K, tiene 3 planetas confirmados.

Medido

Acerca de 2,530 años luz. Para cruzarlo:

La Voyager 1 a la velocidad con la que se alejó durante el año hasta 2026-10-25 (JPL Horizons). Conduciendo: sin parar, sin repostar nunca.

Primer planeta descubierto en 2012, por tránsito y variaciones en el tiempo de tránsito (NASA Exoplanet Archive).

Kepler-46 d — 1.6 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 7 days; about 570 °C, hotter than boiling water; found in 2014 by transit.
Kepler-46 c — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 57 days; about 180 °C, hotter than boiling water; found in 2012 by transit timing variations.
Kepler-46 b — 9.1 times Earth's width, Neptune-sized; its year lasts 34 days; about 270 °C, hotter than boiling water; found in 2012 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.
