Query: Gravitational decoherence of planetary motions   We study the effect of the scattering of gravitational waves on planetary
motions, say the motion of the Moon around the Earth. Though this effect has a
negligible influence on dissipation, it dominates fluctuations and the
associated decoherence mechanism, due to the very high effective temperature of
the background of gravitational waves in our galactic environment.
