Context from the literature
Kepler-413b is a circumbinary planet orbiting stars Kepler-413 A and Kepler-413 B, which respectively are K and M dwarfs. These host stars orbit each other with orbital period of 10.1 days.

Circumbinary planet
Kepler-413 b orbits a binary-star pair rather than a single host — a minority architecture in the confirmed catalogue.
