Other constituents include: eight planets and their moons; a handful of dwarf planets; and vast numbers of smaller objects that fall into three main groups —asteroids (composed largely of rock and metal), comets (made of ice, rock, and dust), and Kuiper Belt objects (largely ice bodies). Also present are appreciable quantities of rock fragments and particles of dust and ice left in the wake of comets. The planets fall into two distinct groups. These are the relatively small, rocky inner planets (Mercury, Venus, Earth, and Mars—see pp.52–53) and the much larger outer planets (Jupiter, Saturn, Uranus, and Neptune)
