Quote (Henry J @ April 25 2012,22:11)
Speaking of orbital mechanics, I have to wonder, if a small object were orbiting a larger object, far enough away from other objects to avoid interference, would the orbit eventually degrade (one way or the other) due to tidal friction, even if both objects were solid?

Another question - given enough time, would Doppler shifts of the gravity waves between the two objects eventually shift the orbit, even if it takes billions (or trillions?) of years for that to be significant?

Henry

Sure.  There is an energy transfer between the objects and that can't be 100% efficient.
