Solar System all have impact craters and tectonic surface features, such as rift valleys and volcanoes. The term "inner planet" should not be confused with "inferior planet", which designates those planets that are closer to the Sun than Earth is (i.e. Mercury and Venus). Asteroids except for the largest, Ceres, are classified as small Solar System bodies and are composed mainly of refractory rocky and metallic minerals, with some ice. They range from a few metres to hundreds of kilometres in size. Asteroids smaller than one meter are usually called meteoroids and micrometeoroids (grain-sized), depending on different, somewhat arbitrary definitions. The asteroid
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.
