How to Identify Stars vs. Planets Based on Light
About this video
Dr. Brian Keating explains that a star’s twinkling, called scintillation, happens because a distant star appears almost point-like and its light is bent differently through turbulent cells of air with different densities, landing on different retinal cells or camera pixels. Keating says planets can be identified by the opposite feature: they do not scintillate, so their lack of twinkling distinguishes them from stars.
Key takeaways
- Keating explains twinkling as scintillation caused by atmospheric turbulence.
- Keating says planets are identifiable because they do not scintillate.
