Star Brightness & DistanceConceptual concept
Check understanding
- Explain that the sun is a star, and it appears much brighter because it is much closer to Earth
- Describe how a torch looks brighter close up and dimmer far away as an analogy
- Argue that differences in apparent brightness of stars are mainly due to their different distances from Earth
“Can your child explain why the sun looks so much brighter than other stars, even though many stars are actually bigger — it's because the sun is much closer to us?”
