Abstract: One of the three classic tests of general relativity is the perihelion precession of mercury,which is resulted from the angular motion modification. In fact,there is modification to the radial motion which leads to the contraction of the orbit,and this modification is up to order of 10 km which can be measurable duo to advances of distance measurement technology.

Key words: general relativity, perihelion precession, mercury orbit, radial position
