Question

why the stars appears higher than there actual position

plz its urgent!!!!!

Answer 1

The stars seem to be higher in the sky than they actually are due to atmospheric refraction.As the light rays from a star pass through the different layers of atmosphere (density of layers increasing downwards), they suffer atmospheric refraction from a rarer to a denser medium. So they bend towards the normal at each layer. Due to continuous refraction, the light from the star appears to come from a point which is actually higher than the star.

Answer 2

it is due to the atmospheric refraction.the light rays from the star travels from rarer to denser medium so ,the star appears higher than their actual position.
