Answer 1

Hey mate..
==========

Your question :- Stars seem higher than they actually are . Why ?

::::::::::::::::::::::::::::::::::::::::::::::

The Reason of your question is :--
~~~~~~~~~~~~~~~~~~~~~~

The starlight , on entering the earth's atmosphere undergoes refraction continuously before reaching the Earth. The atmospheric refraction occurs in a medium of gradually changing refractive index. Since , the atmosphere bends starlight towards normal, the apparent position of the star is quite different from its actual position. The star thus, appears slightly higher than its actual position only when viewed near the horizon.

LOL .

Answer 2

Stars seem higher 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 denser medium.
Hope it helps you!!
