circumbinary planet

(exoplanet orbiting two stars)

A circumbinary planet is an extra-solar planet orbiting both stars of binary star. The first such system was identified in 2003 and as of 2014, about 15 identifications have been confirmed.

The orbit of such a planet must be beyond a certain critical radius or radius of stability to remain stable, generally at least 2-4 times the semi-major axis of the stars' orbits.
