Feb 8, 2020 at 19:03 comment added Astrid_Redfern Incidentally, I thought I'd try plugging the differences between the Earth and Moon's radii into this answer to another question: worldbuilding.stackexchange.com/a/147535/61035 - complete with some over-simplifying assumptions such as Earth and Moon being roughly the same distance from the Sun and the mass of each being uniform throughout. I thought the two situations might have enough similarity for this to be of use. While this gave a higher figure for the Earth's radius loss, it still came down to the same thing - the asthenosphere was the layer exposed at the end of it.

Jan 27, 2020 at 22:03 comment added Astrid_Redfern Good gracious! I didn't realise quite how complex my question was, or that someone would be willing to put this level of effort into working out the answer. Many thanks indeed for that!
