What a learner can do afterwards

  • State that the Sun is a star, not a unique type of object
  • Explain that the Sun appears bigger and brighter than other stars because it is much closer
  • Describe the solar system as the Sun at the centre with planets orbiting around it

The lesson

You already know the Sun warms our days, and stars twinkle in the night sky. Here is the surprise: the Sun is a star too. It is simply the one that lives closest to us.

Try it together

Mia held a flashlight close to her face, and it looked huge and bright. She walked across the yard and held up the very same flashlight, and now it looked tiny. The Sun is like that flashlight. It is a star, the same kind of thing as the ones at night, it just happens to be nearby.

Good to know

If the Sun were moved as far away as other stars, it would shrink down to a tiny twinkle too. Distance is the trick.

The Sun is a star, just the closest one, and it sits at the centre while all eight planets orbit around it.
