By tourists?

That sounds like you think “the third world” is some group that collectively decides on the same thing. But at the same time you haven’t given them any agency otherwise they would ban tourists from entering.

I thought the reference point was the top of the head not the back

No because when you look left your head doesn’t tilt right. When you look up your head tilts backwards

I mean that’s literally the point the image is trying to make. The last sentence says the point is outside the sun for Jupiter.

I don’t think nitpicking the title achieves anything and it’s not even misleading unless it’s only taken in isolation.
