Planets do not twinkle because:

Q.) Planets do not twinkle because:

(a) Planets are not a source of light.

(b) The shift in their position (as compared to stars) is smaller.

(c) they reflect high intensity light reaching them.

(d) both (a) and (b) are true

Ans: (d) both (a) and (b)

Explanation: Planets do not twinkle because:

(1) Planets are not a source of light. Instead, they reflect low intensity light reaching them. (2) They are also closer to the Earth than the distant stars. Hence, the shift due to atmospheric refraction is smaller. (3) As the planets are closer, planets appear larger in comparison to the stars. Hence, the shift is not enough for the planets to twinkle.
