Question

State whether the following statement is true or false:
The planets twinkle at night due to atmospheric refraction of light.

Answer 1

False. The planets do not twinkle at all because of the atmospheric refraction of light. As the planets are large bodies and very close to the earth, the continuously changing atmosphere cannot cause much deviations in the light coming from the planets. The brightness of the planets remains the same and they do not appear to twinkle.
