Naming the Planets

Science · Space Systems & Earth's History · language

Name the planets in our solar system in order from the Sun and use vocabulary for space — planet, star, sun, moon, satellite, orbit, solar system, galaxy, universe, asteroid, comet — applying these correctly when describing the structure of the solar system and objects we see in the sky

What mastery looks like

  • Name the eight planets in order from the Sun without prompting
  • Use 'orbit' correctly to describe the movement of planets around the Sun and moons around planets
  • Distinguish between a planet, a moon, a star, and an asteroid using the correct vocabulary

Check your understanding

Can Naming the Planets name the planets in order from the Sun — and explain the difference between a star, a planet, and a moon?

Prerequisites
