**Abstract:**

Although many scholars consider that original non-closed and
non-symmetric solution for planetary motion equation of general relativity can be
used to solve the problem of advance of planetary perihelion, it has some
shortcomings really. This paper discusses the closed and symmetric solution for
planetary motion equation of general relativity, and that means that general
relativity cannot be used to solve the problem of advance of planetary perihelion.
Also, if the solution for planetary motion equation of general relativity is unique,
then the non-closed and non-symmetric solution including infinite terms should
tend to the closed and symmetric solution. According to "partial and temporary
unified theory of natural science so far" including all the equations so far related to
natural science and its variational principle, the optimization method can be used to
reach the optimal approximate closed and symmetric solution for problem of
advance of planetary perihelion. On the basis of the closed and symmetric solution,
the planetary orbit should be a rotating ellipse or a rotating approximate ellipse;
namely the advance of planetary perihelion is the combined result of two motions:
