★ Twinkling ★
1. Twinkling of stars is due to the atmospheric refraction of starlight.
2. The atmosphere bends the starlight towards the normal. The apparent position of star keeps on changing due to the physical condition of the atmosphere.
3. The stars are very distant, they are approximately point sized source of light.
