Figure 1: Earth is the third planet from the sun, with Mercury and Venus in locations 1 and 2, and Mars just beyond the Earth, 4th from the sun. In the above depiction of our solar system, there are 9 planets, including Pluto, which is farthest from the sun. In 2006, scientists demoted Pluto from a planet to a “dwarf planet”, leaving the 8 planets that are most widely recognized as comprising our solar system.1
