Planet Nine Planet Nine Planet Nine is a hypothetical planet in the outer region of the Solar System. Its gravity could explain the unlikely clustering of orbits for a group of extreme trans-Neptunian objects (eTNOs) that orbit beyond Neptune with average distances greater than 250 AU. These eTNOs tend to have their points of closest approach to the Sun clustered in one direction, and many of their orbits have a similar tilt. This evidence suggests that the gravity from a large undiscovered object is influencing the orbits of the most distant known Solar System objects. This undiscovered super-Earth-sized planet would have an
Terra di Lavoro 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. The Terra di Lavoro was originally a giustizierato (justiciarship) and then a province of the Kingdom of Sicily, later Kingdom of Naples. After the
