We study solutions of the Newtoniann-body problem which tend to infinity hyperbolically, that is, all mutual distances tend to infinity with nonzero speed asor as. In suitable coordinates, such solutions form the stable or unstable manifolds of normally hyperbolic equilibrium points in a boundary manifold “at infinity”. We show that the flow near these manifolds can be analytically linearized and use this to give a new proof of Chazy’s classical asymptotic formulas. We also address the scattering problem, namely: for solutions which are hyperbolic in both forward and backward time, how are the limiting equilibrium points related? After proving some basic theorems about this scattering relation, we use perturbations of our manifold at infinity to study scattering “near infinity”, that is, when the bodies stay far apart and interact only weakly.
