On the Secular Recession of the Earth-Moon System as an Azimuthal Gravitational Phenomenon (II)

Authors: Nyambuya G. G., Makwanya T., Tuturu B. A., Tsoka, W.

We here apply – albeit, with improved assumptions compared to our earlier work (Nyambuya et al., Astron. & Astro-phys. S. Sci. 358(1) : pp.1 − 12, 2015); the ASTG-model to the observed secular trend in the mean Sun-(Earth-Moon) and Earth-Moon distances thereby providing an alternative explanation as to what the cause of this secular trend may be. For the semi-major axis rate of the Earth-Moon system, we now obtain a new value of about +3.00 cm/yr while in the earlier work we obtained a value of about 5.00 cm/yr. This new value of +3.00 cm/yr is closer to that of of Standish (2005)'s measurement of (7.00 ± 2.00) cm/yr. Our present value accounts for only 43% of Standish (2005)'s measurement. The other 57% can be accounted for by invoking the hypothesis that the θ-component of the angular momentum maybe non-zero. In the end, it can be said that the ASTG-model predicts orbital drift as being a result of the orbital inclination and the Solar mass loss rate. The Newtonian gravitational constant G is assumed to be an absolute time constant
