Question

Quizplus · Accepted Answer

C  D  A large orbit around both stars in a close binary system (A) can be stable if the orbit is far enough from the stars. An orbit close to one of the stars in a close binary system (C) can be stable if the planet is close enough to one star to be gravitationally bound to it. A large orbit around both stars in a wide binary system (D) can also be stable if the stars are far enough apart. A "figure-of-eight" orbit (B) is generally unstable due to the complex gravitational interactions.
