Why Does the Moon Travel With Us When We Walk or Ride?
The moon does not really travel with us. It only seems to do so. The moon is so far away that when we walk a block or two or a hundred, we cannot notice any relative difference in the relative positions of the moon and ourselves. When a thing is close at hand we can notice every change in our position toward it, but when it is far away the change of our position toward it is so slight that it is hardly perceptible. A very good way to illustrate this is to ask you to recall the last time you were in a railroad train looking out at the scenery in the country. The telegraph poles rush past you so fast you cannot count them. The cows in the pasture beside the railroad do not seem to go by so fast. You can count them easily. The tree farther over in the next field does not appear to be moving but slightly, while the church steeple which you can see far in the distance, does not go out of sight for a long time—in fact, seems almost to be moving along with you. The moon is just like the church steeple in this case, except that it is so much farther away that it seems to travel right with you. It is all due to the fact as stated at the beginning of this answer, that the relative positions of yourself and the moon are only slightly changed as you move from place to place, so slight in fact as to appear imperceptible.
