Despite these many complexities, celestial mechanics often offer predictable methods for tracking heavenly bodies.

Occasionally, astronomers discover a previously unseen mass zipping across the sky as a point of light. Knowing the size, speed, and orbit of such things is helpful. Here in the United States, we have people who study such things for a living.

The National Aeronautics and Space Administration (NASA) searches for and identifies Near Earth Objects (NEOs), having discovered over 30,000 they have cataloged, transforming our understanding of our neck of the universe.1 They identified a unique body in space in 2002, as shown in Figure 3.1.
