Come è stato scoperto
Primo pianeta scoperto nel 2010 con le variazioni dei tempi delle eclissi (NASA Exoplanet Archive).
I suoi pianeti
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.
