Q. 11. Explain why the
planets do not twinkle.
Answers
Answer:
Planets appear larger to human eyes as compared to stars because they are closer. As the angle subtended by the planets at the human eye is more, the shift in their position(as compared to stars) is smaller. Since, the shift is smaller, they do not twinkle
Explanation:
Unlike stars, planets don't twinkle. Stars are so distant that they appear as pinpoints of light in the night sky, even when viewed through a telescope. Because all the light is coming from a single point, its path is highly susceptible to atmospheric interference (i.e. their light is easily diffracted)
Answer:
The main reason for this is that planets do not emit their own light. They reflect other star's light or just produce their light from heat. As the stars are far away from Earth, their light comes from a very long distance and can be easily refracted by the Earth's atmosphere, which is the reason why stars twinkle. Coming to the main question, planets do not twinkle whichever planet we can see from our naked eye/telescopes are very close to Earth as compared to stars. This makes their light's intensity far much stronger than the light from the stars. Thus, our atmosphere is not able to conspicuously refract the light so as to make us think that the planets are twinkling.
