While coordinating the exodus, the Command Centre staff sights a celestial body at extreme range. After Computer sluggishly offers vague estimates regarding its identity, calculates the object to be a small planet with a gravitational pull approximating the Moon's—insufficient to affect their course.

Before they can investigate this possibility, the staff is distracted by the sight of a spacecraft streaking across the screen.
