Come è stato scoperto

Primo pianeta scoperto nel 2013 con le variazioni dei tempi di transito e il transito (NASA Exoplanet Archive).

I suoi pianeti

Kepler-411 e — 3.3 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 32 days; about 230 °C, hotter than boiling water; found in 2018 by transit timing variations.
Kepler-411 c — 4.4 times Earth's width, Neptune-sized; its year lasts 8 days; about 570 °C, hotter than boiling water; found in 2016 by transit.
Kepler-411 b — 2.4 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 3 days; about 870 °C, hotter than boiling water; found in 2013 by transit.
Kepler-411 d — 3.3 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 58 days; about 140 °C, hotter than boiling water; found in 2018 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.
