Stability of the Solar System that keeps the far side of the Moon away from the Earth. Mercury is in a 3:2 spin–orbit resonance. The planets' orbits are chaotic over longer timescales, such that the whole Solar System possesses a Lyapunov time in the range of 2–230 million years. In all cases this means that the position of a planet along its orbit ultimately becomes impossible to predict with any certainty (so, for example, the timing of winter and summer become uncertain), but in some cases the orbits themselves may change dramatically. Such chaos manifests most strongly as changes in eccentricity, with some planets' orbits
Terra di Lavoro of Caserta was created, including communes of the central Terra di Lavoro (including Aversa) previously part of the province of Naples, Benevento and Campobasso. Terra di Lavoro Terra di Lavoro (Liburia in Latin) is the name of a historical region of Southern Italy. It corresponds roughy to the modern southern Lazio and northern Campania and upper north west and west border area of Molise regions of Italy. In Italian the name means literally "Land of Work", but in fact derives from the ancient "Liburia", a territory north of Aversa which took its name from the ancient tribe of the Leborini.
