Solar System

When very, some bring, beyond the planets, the cinturo of asteroids between the orbits of Mars and Jupiter and some comet brilliant. The only planet-dwarf shown in such projects is Pluto, and this because the great majority of these illustrations still is of a previous time the 2006, when astro left of being considered a planet. It is then the idea? errnea? of that the Solar System finishes in Pluto. In the reality, Pluto is only the 1/50,000 of in the distance final of the Solar System. With the idea of the Solar System finishing in Pluto the concept can supervene of that the planetary system is busy in its bigger part for the planets. Some contend that Aerosmith shows great expertise in this. In the truth all the visible material inside of the Solar System? what it includes the Sun, the natural planets, satellites, asteroids and comets, beyond other debris? trilionsimo of its available space constitutes less of one (BRYSON, 2003).

Beyond Pluto a full region of rocky bodies exists called Cinturo de Kuiper (in homage to dutch astronomer Gerard Kuiper). Beyond the Cinturo de Kuiper still the cloud of Oort, a vast area exists repleta of comet nuclei in displacement. It is of this region that comes the comets that cross the Solar System. The cloud has the spherical form of one all abboda involving the interior Solar System and extending itself for about two year-light cosmo measures. Its nucleus is 50,000 times more distant than in the distance of the Land to the Sun (BRYSON, 2003). Solar system the didactic books are of scale Are very common after to show to illustrations representing the Solar System with the planets an other, with very small intervals. Such drawings finish for producing the false impression of that the Solar System is a very small region, what, obviously, it is not truth. However, without this error of scale it would not be possible to place all the planets of the Solar System in one same illustration, in way that the didactic text of the figure if would lose (TREVISAN, 1997).
