Objects in the Solar System[edit | edit source]

  • Dwarf planets - great objects (not necessary smaller than the planets), that turn around the Sun, but are part of clouds of objects, named "belts", such as the Asteroid belt or the Kuiper belt. Pluto, once said to be the ninth planet, is the most famous. Eris and Ceres are also dwarf planets.
  • Asteroids (or meteoroids) - are smaller objects, that have no regular shape : they look like immense blocks of rocks in the space. Most of them form a vast group called the Asteroid belt. Other can be scarced in the Sun System.
  • Satellites - are various size object, that don't turn directly around the Sun, but around a planet, a dwarf planet or an asteroid.
  • Comets - are objects made of ice and dust that turn around the Sun in a peculiar way, that seem to pass through the Sun System.
