Deepsix (The Academy #2) By Jack McDevitt (Audiobook)

In the year 2204, tragedy and terror forced a scientific team to prematurely evacuate Maleiva Ill. Twenty-one years later, the opportunity for scientists to study this galactic rarity—a life-supporting planet—is about to vanish forever as a rogue gas giant has invaded the planetary system on a deadly collision course with the world they are now calling Deepsix.
