The big idea
Stars are distant suns: enormous glowing spheres that look tiny because they are very far away.
The Sun is the nearest star. Other stars differ in size, temperature, color, age and brightness.

HOW SCIENTISTS KNOW
Spectra reveal star temperatures and chemistry; parallax and other measurements reveal distance.

!A COMMON WRONG MODEL
Stars are tiny points attached to a dark sky.
✓REBUILD IT WITH EVIDENCE
Stars are enormous spheres; distance makes them appear point-like.
A scientifically true sentence can still create a false picture. This repair makes the relationship visible.
Take learning into real life
Try it together
With an adult, observe one safe patch of sky for five minutes. Record time, direction, color and motion before offering an explanation. Never look at the Sun. Connect what you notice to stars are distant suns using star and Sun.
