About: Small Solar System body   Sponge Permalink

An Entity of Type : owl:Thing, within Data Space : 134.155.108.49:8890 associated with source dataset(s)

This encompasses all minor planets other than those reclassified as dwarf planets, i.e.: * the classical asteroids, with the exception of Ceres; * the centaurs and trojans; * the trans-Neptunian objects, with the exception of Pluto, Haumea, Makemake and Eris; * all comets. It is not presently clear whether a lower size bound will be established as part of the definition of Small Solar System Bodies in the future, or if it will encompass all material down to the level of meteoroids, the smallest macroscopic bodies in orbit around the Sun. (On a microscopic level there are even smaller objects such as interplanetary dust, particles of solar wind and free particles of hydrogen.)

abstract
  • This encompasses all minor planets other than those reclassified as dwarf planets, i.e.: * the classical asteroids, with the exception of Ceres; * the centaurs and trojans; * the trans-Neptunian objects, with the exception of Pluto, Haumea, Makemake and Eris; * all comets. It is not presently clear whether a lower size bound will be established as part of the definition of Small Solar System Bodies in the future, or if it will encompass all material down to the level of meteoroids, the smallest macroscopic bodies in orbit around the Sun. (On a microscopic level there are even smaller objects such as interplanetary dust, particles of solar wind and free particles of hydrogen.) Except for the largest - which are in hydrostatic equilibrium - moons differ from Small Solar System Bodies not in size, but in their orbits. Moons' orbits are not centered around the Sun but around other Solar System objects such as planets, dwarf planets, and even Small Solar System Bodies themselves. Some of the larger Small Solar System Bodies may be reclassified in future as dwarf planets, pending further examination to determine whether or not they are in hydrostatic equilibrium. The orbits of the vast majority of Small Solar System Bodies are located in two distinct areas, namely the asteroid belt and the Kuiper belt. These two belts 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.
