Arrange the eight planets of our solar system in the correct order of their average distance from the Sun, from closest to farthest. Our solar system formed approximately 4.5 billion years ago from a collapsing cloud of gas and dust, leaving the Sun at the center surrounded by eight planets in nearly circular orbits. The terrestrial planets - Mercury, Venus, Earth, and Mars - Occupy the inner solar system, rocky worlds shaped by heat and geological activity. Beyond the asteroid belt lie the gas giants Jupiter and Saturn, massive worlds with their own extensive moon systems and iconic features like Saturn's rings. The outer solar system belongs to the ice giants Uranus and Neptune, cold and remote worlds only visited by Voyager 2. Every student should know the order of the planets - Test yourself here.
Remaining questions will count as incorrect.
