Question:
How can the moon spin on an "axis" just like the earth,
if we see the same side of the moon at all times? I can see how it
orbits
the earth on a plane, but if it spun on an axis (completing a 360) as it
orbits the earth, then we would see all sides of the moon?
Replies:
You just have to try it yourself: walk around your mailbox, facing it
all the time. Sometime during your trip you'll see your house in the
background; sometime later you'll see the street. You MUST be spinning
if you see these things, yet your mailbox never sees the back of your
head.
