Radial velocity observations of a binary star system have led to the discovery of a gas-giant circumbinary planet, BEBOP-1 c, which is 65 times more massive than Earth, with an orbital period of 215.5 days. The binary system also hosts a smaller, inner transiting planet, TOI-1338 b, making this system a rare multi-planet circumbinary system.
