Question

a. Explain why do the planets not twinkle but
the stars twinkle.
b. What will be the colour of the sky, when it
is observed from a place in the absence of
any atmosphere?​

Answer 1

$\huge\star\underline{\mathtt\red{A}\mathtt\green{N}\mathtt\blue{S}\mathtt\purple{W}\mathtt\orange{E}\mathtt\pink{R}}\star\:$

a.) 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

b.) The colour of the sky would be black when observed from a place in the absence of any atmosphere. This is because, in absence of atmosphere, no scattering of light would take place.

Hope it helps.........
