Estrella con 2 planetas conocidos

NN Ser

NN Ser, una estrella WD, tiene 2 planetas confirmados.

Medido

Acerca de 1,680 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 2010, por variaciones en el tiempo de los eclipses (NASA Exoplanet Archive).

NN Ser c — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 19 Earth years; found in 2010 by eclipse timing variations.
NN Ser d — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 8 Earth years; found in 2010 by eclipse timing variations.

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.
