In celestial mechanics, Jacobi's integral (named after Carl Gustav Jacob Jacobi) is the only known conserved quantity for the restricted three-body problem problem [1]; unlike in the two-body problem, the energy and momentum of the system are not conserved separately and a general analytical solution is not possible. The integral has been used to derive numerous solutions in special cases.
