Grades 5-8
Earth in the Solar System

  • The Earth is the third planet from the Sun in a system that includes the moon, the Sun, other planets and their moons, and smaller objects, such as asteroids and comets.
  • Most objects in the solar system are in regular and predictable motion.
  • Gravity is the force that keeps planets in orbit around the Sun and governs the rest of the motion in the solar system.
