  This article produces wave equations and constructs traveling wave solutions
that are intimately related to Newton's equations of celestial mechanics. The
traveling wave solutions are expressed in ``closed form'' in terms of
elementary functions. They are specialized to the 2-body and the relative
2-body problem. The traveling wave solutions disclose the shape and position of
wave fronts emanating from collisions by determining the location of the
singularities of the traveling wave solutions.
