Abstract—

An algorithm for the numerical solution of Kepler’s equation with machine precision is presented. The convergence of the iterative sequence of Newton’s method is proved for the indicated initial approximation. The problem of finding a numerical solution to Kepler’s equation as a floating point number is formulated. Aspects related to computations near machine zero are taken into account. We analyzed the accuracy of the possible result. A problem is identified that arises when tending for the highest possible accuracy and a solution is proposed. An estimate is given of the computer time required to solve Kepler’s equation by this method.
