The Vast Scale of Space

Science · Space Exploration · conceptual

Describe the scale of the universe in nested layers: Earth is one planet in our solar system, the Sun is one star among billions in the Milky Way galaxy, and the Milky Way is one galaxy among billions in the universe

Sign in to track this

What mastery looks like

  • State that the Milky Way is our galaxy and it contains billions of stars
  • Explain the hierarchy: planet → solar system → galaxy → universe
  • Use a comparison to convey cosmic scale (e.g. if the Sun were a football, Earth would be a peppercorn 26 metres away)

Check your understanding

Can The Vast Scale of Space describe how our place in the universe works — that we’re on a planet in a solar system in a galaxy among billions of galaxies?
