Question

Quizplus · Accepted Answer

According to Kepler's third law, the period of the binary system is dependent on the distance between the two stars (semi-major axis) and their masses. As the stars are moved farther apart, the distance between them increases, resulting in a longer semi-major axis. Therefore, according to Kepler's third law, the period would increase.
