since the stars are very far away , the telescope can only make them look brighter but not larger .
A star has very high temperature .
There are billions of stars in the celestial sphere .


A planet has no light of it's own.It shines by reflecting the light I of sun .
planets do not twinkle at all.
Since planets are very much closer to the earth than the stars are ,their motion around the sun is noticeable as a daily shifting of relative position in the sky .
Most planets on the other hand are near enough to the ears to be magnified by the telescope .
Planets have low temperatures.
