Perception of far object that is in motion

    Why do objects that are distant and moving appear to be moving slowly than the objects that are close?

    By this I assume you mean why they do not move as much in your field of view. The reason is that in order to change by the same angle in your field of view, an object which is further away must move further.

    For the same reason that distant objects appear smaller.

    Google 'parallax'! This is one of the most accurate ways that astronomers measure distances to (nearby) stars.
