Kepler-411 is a binary star system. Its primary star Kepler-411A is a K-type main-sequence star, orbited by the red dwarf star Kepler-411B on a wide orbit, discovered in 2012.
The primary star's surface temperature is . Kepler-411A is similar to the Sun in its concentration of heavy elements, with a metallicity Fe/H index of 0.11, but is much younger at an age of 212 million years.
Kepler-411A exhibits significant starspot activity, with starspots covering 1.7% of the stellar surface. Darker starspots are concentrated around the equator of the star. Kepler-411A exhibits differential rotation, but with smaller amount of differential shear compared to the Sun.
The companion Kepler-411B is away from Kepler-411A. It is a red dwarf and a flare star.[1]
In 2013, one planet, named Kepler-411b, was discovered, followed by planet Kepler-411c in 2016. Third planet in system detected by transit method, d, along with e detected by radial velocity method, were discovered in 2019.
