And when we do that, we are attributing dynamical properties that really belong to the Sun, to the different planets. That is, we're adapting and modifying the orbital parameters of the different bodies of the solar system, to account or compensate for what really is the Sun's own movement. And although at the quantitative level the effects could be very small(in the relative short term), there's also a qualitative aspect, that must also be considered and reflected upon. > > >> That must and will change in the future; we should start to think >> about >> the movement of the Sun as a real one, in the same way as we consider >> today the movements of the Moon and Earth as proper. >> >> Mauro >> > > I think it is true that astronomers do so when precision requires, as > when predicting future close star locations.

Particularly if those interactions could involve new physics or the possibility of developing new astrophysical theories. And besides that, there's again also the qualitative aspect, that could turn out to be more important and significative than the quantitative one. Best regards, Mauro
