Question

Why stars do appears to be at rest, though they are moving very fast? pls tell this is the hardest

Answer 1

Answer:

The first is because the Earth is spinning and second because the Earth itself is moving around the Sun. Each day the Earth will have moved one 365th of its orbit around the Sun. The result is that we see some different stars coming into view as the Earth spins from night to night and other stars move out of view. As some stars disappear from view and some new come in view we think they are moving.
