In a first term you learn that all the drawing of the solar system are fake. But fake not because earth is flat or in the center of the system. Only fake because all the representation of the planets to be visible on a page needs to enlarge too much each of them to make them visible for a human eye resolution.

And suddenly, in a second term, which this representation which is fair to planet scale and distances scale, you just realize that The Solar System, the one you are leaving in is amazing huger and in the same time, you are understanding that : the universe is far more more amazing huger than that we can imagine. Consequences :
- the Earth, is far more smaller than what you can imagine ;
- we really need to protect Her.
