Solar System - Trans-Neptunian Region

Trans-Neptunian Region

The area beyond Neptune, or the "trans-Neptunian region", is still largely unexplored. It appears to consist overwhelmingly of small worlds (the largest having a diameter only a fifth that of the Earth and a mass far smaller than that of the Moon) composed mainly of rock and ice. This region is sometimes known as the "outer Solar System", though others use that term to mean the region beyond the asteroid belt.

Famous quotes containing the word region:

    Myth is the hidden part of every story, the buried part, the region that is still unexplored because there are as yet no words to enable us to get there.... Myth is nourished by silence as well as by words.
    Italo Calvino (1923–1985)
