The great distance of the moon from the earth explains why the moon seems to follow us when we drive in a vehicle and look up at it. When we speed along a road, we notice that everything moves past us. Trees, houses, the road, fences – all fly past us in the opposite direction. We naturally expect the moon also to be flying past us. When this does not happen, we have the sensation that it is “following” us. It happens because the distance of the moon from the earth is quite great. Compared to the distance our vehicle travels in a few minutes, that distance is enormous. So as we move along, the angle at which we see the moon hardly changes. In fact, we could go along a straight path for miles and the angle at which we could see the moon would still be basically the same. And as we notice everything else flying past, we get that feeling of the moon following us.
