Answer 1

Answer:

The stars twinkle in the night sky because of the effects of our atmosphere. When starlight enters our atmosphere it is affected by winds in the atmosphere and by areas with different temperatures and densities. This causes the light from the star to twinkle when seen from the ground.

Explanation:

The answer is the planets actually do twinkle. In fact, everything outside our atmosphere, anything we're looking at outside your atmosphere does twinkle due to the effect that we discussed. However, we can't notice the twinkling effect of the planets because planets appear bigger in size to us.
