Reasonably accurate starting positions for the state of the Solar System on 1 January 2000. If you run this at lower simulation speeds, it should predict positions of the major planets for at least several decades, maybe more. The planet Mercury is likely to be the least accurately predicted because of the high acceleration it undergoes (and because of relativistic effects which Gravitorium doesn't take into account).
Note that without diameter exaggeration, in this simulation we are too far away from the sun and planets to see them as anything other than dots. Check off the "Allow Diameter Exaggeration" box to see an accurate representation.
