The difference δr in the celestial body positions in the mean and osculating orbits is a quasi-periodic function of time. Estimating the norm ||δr|| for deviation is interesting to note. Earlier, the exact expression of the mean-square norm for one problem of celestial mechanics was obtained: a zero-mass point moves under the gravitation of a central body and a small perturbing acceleration F. The vector F is taken to be constant in a co-moving coordinate system with axes directed along the radius vector, the transversal, and the angular momentum vector. Here, we solved a similar problem, assuming the vector F to be constant in the reference frame with axes directed along the tangent, the principal normal, and the angular momentum vector. It turned out that ||δr|2 is proportional to a6, where a is the semi-major axis. The value ||δr|2 a-6 is the weighted sum of the component squares of F. The quadratic form coefficients depend only on the eccentricity and are represented by the Maclaurin series in even powers of e that converge, at least for e < 1.
