It involves two stars with planets, where the radial velocity method provides maximum velocity shifts for each planet. The task is to determine the orbital period of the planet around Star B using the known orbital period of the planet around Star A and the relationship between velocity shifts and orbital periods. The solution reveals that the orbital period of the planet around Star B is 4.6 years."}
