Alex asked:
Care to elaborate why Mercury is difficult to model? Is Mercury hard to
model because of its proximity to an enormous gravitational mass?
I think you have it right, close to the Sun. Explosions are constantly happening on the sun, shooting matter up into space. Each time this happens Mercury's orbit is perturbed.

You are right, of course, but we can model relativity, so that's not a cause of the inability to predict! <grin!> Tim (who has too much time on his hands right now ...)

We can model relatively only to a degree. Solving the full general relativity equations is beyond our present capability, I understand.

Sounds like you need to buy yourself some of Dr Wells' Patent Time Machine and Hand Cleaner! Specially developed for those trips where you hit so many clouds of Time Flies that you and your Time Machine are covered with the dreaded Gunk Of Time! But how could you have too much time on your hands right now? -- David W. Jones gnome@hawaii.rr.com authenticity, honesty, community http://dancingtreefrog.com

Still raining in Houston more or less continuously, and not a good idea to try and go anywhere. By the looks of it things will be better by Thursday. Tim On Tue, Aug 29, 2017 at 2:30 AM, david <gnome@hawaii.rr.com> wrote:
