The four planets closest to the Sun are called the terrestrial planets. The terrestrial planets share several characteristics. These inner planets are small and rocky. They have few or no moons, and are located inside the Solar Systems's asteroid belt. The terrestrial planets are more dense than the outer or Jovian planets. Although they are all rocky, their varying distances from the Sun create drastically different conditions on each planet.
