Small Solar System body possess some internal structure related to perturbations by the major planets (particularly Jupiter and Neptune, respectively), and have fairly loosely defined boundaries. Other areas of the Solar System also encompass small bodies in smaller concentrations. These include the near-Earth asteroids, centaurs, comets, and scattered disc objects. Small Solar System body A small Solar System body (SSSB) is an object in the Solar System that is neither a planet, a dwarf planet, nor a natural satellite. The term was first defined in 2006 by the International Astronomical Union (IAU) as follows: "All other objects, except satellites, orbiting the Sun shall be
Social gravity a manner "analogous in all cases, by which the center of gravity in the solar system" held the planets in their orbits. In making this analogy, Pownall's notion of 'social gravity' drew upon earlier visions of social cohesion, particularly ideas of sociability in eighteenth-century Britain. These ideas, in turn, were often predicated upon Stoic notions of cosmopolitanism, expressed by the key term oikeiôsis, in order to stress the "moral" imperative for like-minded humans to forge bonds dedicated to the common good. Social gravity Social gravity was an application of Newtonian gravity to the system of commerce influence. For instance, in
