General description of the fabric of observable structures in the universe and their motions had been presented currently, but the quantitative work of these motions is still not yet formed. Here we specify that within a series of hierarchical two-body systems, the motion of an object relative to another object is determined by both the number of motion between them and its magnitude. The test result shows that during the past 50 years the average difference of right ascension (α) and declination (δ) for the Sun and planets between this model and JPL’s Horizons system(equivalent to observation) are respectively 4.13 degrees and 1.07 degrees. Given a longitudinal cover of 360 degrees and latitudinal cover of 180 degrees, the average error for right ascension (α) and declination (δ) are respectively 1.19 % and 0.59 %. The advance of the perihelion of Mercury and Lunar acceleration are further discussed.
