I agree completely. It is interesting to see what you get when you ask
people which of three pictures is the best illustration of the earth's
orbit around the sun. The near circle, an elongated ellipse with the
sun at a focus or an elongated ellipse with the sun in the center.
Almost no one picks the near circle.

To me, the source of this mistake is the textbooks. The Earth is always
shown from a side view with a very elongated ellipse and the point is made
that the sun is at one of the foci. What other conclusion do we expect
students (and often their teachers) to draw from this other than the
mistaken
explanation for the seasons?
