How many sides does our moon have. I’ve seen only one, but I guess that’s relative to your position in relation to the moon. So, since there are an infinite number of positions one could view the moon from, there are an infinite number of sides to the moon.
Everyone is thinking of the circle and how it would appear if drawn on a sheet of paper. You need to think three dimentionally and view the circle from the “side” so that it would appear to you as a line of fixed length. Now rotate your viewing position around the center of the circle on the same plain as the circle and there you go. An infinite number of sides.
But the moon has only one “ far side”
I agree this is not a 1st grade question and is a trick to get the kids to think everything is relative.
There are no sides though. A side is defined by two points that have other point/s linearly between the two. Since there is always a point between two points on the curve that is not linear with those two points, there are no sides.
Did you know the moon doesn’t rotate? We always see the same side. Did you know the moon moves away from earth about 6” a year?
