%0 Journal Article %T Gravitational decoherence of planetary motions %A Serge Reynaud %A Paulo A. Maia Neto %A Astrid Lambrecht %A Marc-Thierry Jaekel %J Physics %D 2001 %I arXiv %R 10.1209/epl/i2001-00286-8 %X 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. %U http://arxiv.org/abs/quant-ph/0102061v1
