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.

Relativity also kicks in on Mercury's orbit due to being so deep in the sun's gravity well. David W. Jones gnome@hawaii.rr.com authenticity, honesty, community http://dancingtreefrog.com
