It is hard to see the motion of stars because of their extreme distance from us
true
false

true

explanation:

motion of star is not visible to us because we define motion as change in position of object.

here since stars are far away from us then as per our reference frame we can see that the position of star at a finite angular position

now let say the star moves by some distance near it's position then we will say that the change in its angular position with respect to our position is given by

here r = distance of star from our position

now as we know that distance of star is very large as compare to change in its position so the change in angular position is very small.

so this small change in angular position is not detectable to us and it seems to be stationary for us.
