Our Solar System

There are 9 main planets and countless comets and meteorites orbiting our Sun - all of which have some degree of influence on the ultimate destiny of the Earth. Recently, Pluto has been reclassified as a 'dwarf planet' , rather than a planet. Since 1992, planets have been found to be orbiting stars outside of our Solar System, and as of December 2011 over 700 such 'exoplanets' have been documented.
