Planets do not twinkle because?

Athey scatter less light

Bthey act as extended source of light

Cthey act as a point source of light

Dthey scatter more light

Answer:

B. they act as extended source of light

Read Explanation:

  • Planets do not twinkle because they act as extended sources of light, so the variations due to atmospheric turbulence are averaged out.

  • Stars twinkle because their light undergoes atmospheric refraction, causing the light's path and the star's apparent position to fluctuate.

  • Planets, being closer to Earth, appear as extended sources of light, and the effects of refraction on their light average out, preventing them from twinkling
