Thisiscalledtotalcollapse. Thefactc=0meansthattheparticlesareable toallcollapsetoasinglelocation. Curiously enough, despite all this there exists a convergent power series solution to the 3-body problem, which was found by Sundman in 1913. Saari gives an accessible account of Sundman's construction in A Visit to the Newtonian N-body Problem via Elementary Complex Variables: Sundman's theorem for the 3-body problem.

A new coordinate form for the Sundman surfaces is obtained. Singular points of the surfaces are determined and constructed. The Sundman stability is investigated. The Sundman stability of the motion of the Moon in the general three-body problem of the Sun-Earth-Moon is established.

The three-body problem is a special case of the n-body problem, which describes how n objects will move under one of the physical forces, such as gravity. These problems have a global analytical solution in the form of a convergent power series, as was proven by Sundman for n = 3 and by Wang for n > 3 (see n -body problem for details).
