Thanks. I don't know Einstein's equations for gravity. An effect of increased density, even if too small to measure for normal matter, will be interesting.

Meanwhile, I suspect the complexities of classical dynamics dominate relativity in the Earth-Moon system: I have read that the slow retreat of the Moon is caused by tidal forces.
