Present the outcome of the past. After the present, the past. The forces that the we have found to be moulding the system to-day must be those that fashioned it earlier. Given, therefore, the condition at the moment, if we apply to it the forces now at work reversed, we shall get the condition that was.
Similarly, we can cast its horoscope for the future, by Taylor's theorem. Unfortunately, the problem is so complicated that no solution, even approximately satisfactory, has yet been obtained; but that the mystery baffles us renders it all the more fascinating.

I. The central body is much larger than its attendants.

III. They travel nearly in one plane.
