Question

Why the stars twinkle but not earth?​

Answer 1

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).

The much closer planets appear instead as tiny disks in the sky (a distinction more easily discerned with a telescope than with the naked eye).( I.e planets are much larger compared to stars) .Their apparent sizes are usually larger than the pockets of air that would distort their light, so the diffractions cancel out and the effects of astronomical scintillation are negligible.

Answer: here u  r

Explanation:

its so becz

1) star is assumed to be a point sized object and even appears to be so it is like if only one ray of light is getting refracted n reaches our eyes

2) earth is not a point sized object , it is a grp of many point sized light rays which while getting refracted trough the atmosphere nullify each others effect

Hope it helps u
