42. One knows, by modern observations that the sun is not fixed or a central point, as they believed it to be in the early days of modern astronomy, but that it advances in space, drawing with it its vast system of planets, satellites, and comets.
Now this march is not casual: it does not wander about in the infinite voids, to be lost far away from the regions assigned to it, its children, and subjects. No; its orbit is measured, concurrently with other suns of the same order as itself, and surrounded like itself with a certain number of inhabited worlds, it gravitates around a central sun. Its movement of gravitation, the same as that of other suns (its brothers), is inestimable by annual observation; for a great number of earthly centuries would hardly suffice to mark the time of one of these astral years.
