Euler's three-body problem In physics and astronomy, Euler's three-body problem is to solve for the motion of a particle that is acted upon by the gravitational field of two other point masses that are fixed in space. This problem is exactly solvable, and yields an approximate solution for particles moving in the gravitational fields of prolate and oblate spheroids. This problem is named after Leonhard Euler, who discussed it in memoirs published in 1760. Important extensions and analyses were contributed subsequently by Lagrange, Liouville, Laplace, Jacobi, Darboux, Le Verrier, Velde, Hamilton, Poincaré, Birkhoff and E. T. Whittaker, among others.
Charles-Eugène Guye Charles-Eugène Guye (October 15, 1866 – July 15, 1942) was a Swiss physicist. He was born in Champvent and died in Geneva. Guye studied physics at the University of Geneva, where he received his doctorate in 1889, studying the phenomenon of optical rotary dispersion.
