While we all know that the Sun is very big and very far away, its actual size and distance from Earth can be hard concepts to grasp. Many Solar System models that we see inaccurately display the relative size of the Sun compared to the planets, and almost all models inaccurately display the true distance between Solar System objects. This isn't due to a lack of astronomical knowledge, but rather the amount of space that an accurate model would require! For example: an accurate model with a marble-sized (one inch in diameter) Earth would call for a nine-foot wide Sun and [...]
