shines in the sky stars appear fixed and clearis actually based on the ability of our eyes to perceive speeds.

This, temporal and spatial resolution of the visual system is also a consequence. But how?

The stars in the sky follow a specific circular path as the Earth rotates.

The Earth rotates on its own axis as well as orbiting the sun, but these movements are too slow to be noticeable in our daily lives. The Earth rotates on its axis approximately every 24 hourswhich means that the stars move across the sky at a certain speed. However, this speed is not high enough to affect our observations.

Moreover Due to the distance of the starschange their apparent positions in the sky by very small angles. The motion of the Earth does not have a great effect on the apparent positions of the stars, because the stars are millions or even billions of kilometers away from us.

The human eye and most telescopes operate with short exposure times.

this too will not be able to observe the movement of stars in the sky for such a short time. Stars, for example, remain virtually stationary during the short exposure times used to take a photo.

Finally the earth’s atmospherecan affect the appearance of stars, but this is commonly known as twinkling and does not cause blur. When atmospheric conditions are right, stars can be seen very clearly and distinctly.

At work Independent of the Earth’s motion These are all reasons why we can still see the stars clearly in the sky.
