Planets do not twinkle because
- a)they emit light of a constant intensity
- b)their distance from the earth does not change with time
- c)they are very far away from the earth resulting in decrease in intensity of light
- d)they are nearer to earth and hence we receive a greater amount of light and, therefore minor variations in the intensity are not noticeable
Correct answer is option 'D'. Can you explain this answer?

Twinkling in stars happen due to refraction of light which they emits..stars twinkle because the light which they emits and comes to earth passes through different different mediums and so there refractive index varies.. hence the light passing through that mediums changes its course...and stars seem like twinkling...in case of nearer planets,the variation in refractive index in less...so they don't seem twinkling...

Understanding Why Planets Do Not Twinkle
The phenomenon of twinkling, or stellar scintillation, is primarily observed in stars rather than planets. Let's delve into the reasons why planets appear stable in brightness compared to stars.
Closer Proximity
- Planets are part of our solar system and are significantly closer to Earth than stars, which are light-years away.
- Their proximity means that the light we receive from them is less affected by atmospheric disturbances.
Greater Light Intensity
- Due to their closeness, planets emit a greater amount of light that reaches Earth.
- This stronger light intensity makes minor fluctuations in brightness less noticeable to the human eye.
Stable Light Emission
- Unlike stars, which are massive and undergo various nuclear processes leading to fluctuating brightness, planets reflect sunlight.
- Their light intensity remains relatively constant, contributing to a steadier appearance.
Atmospheric Effects
- Stars twinkle due to the Earth's atmosphere, which causes the light from distant stars to bend and scatter.
- Since planets are nearer, the light distortion is minimal and does not produce the same twinkling effect.
In summary, the correct answer is option 'D' because planets, being nearer to Earth, deliver a more stable light source. This proximity means that any minor variations in their light intensity are not easily perceived, distinguishing them from the twinkling stars in our night sky.
