The radiative and particulate loss of mass by the Sun, -9.13*10^-14 Solar masses per year or more causes the orbits of the planets to expand at the same rate, and their periods to lengthen at twice this rate. Unfortunately, under the present definition of the Astronomical Unit (AU) based on the fixed Gaussian gravity constant kGS = 0.01720209895 (AU)^1.5/day, the value AUmet of the AU in meters must decrease at 1/3 this rate, all these rates being expressed logarithmically. The progress of th...
