Solar System and Distance
Earth is a big place.
If you could drive around the entire planet, it would take more than sixteen days of non-stop driving at highway speeds. But. compared to some of the planets in our solar system, it's pretty small. We often see planets displayed as similar in size to make details on smaller planets easier to see. Because of the great distances between planets, and the planets relatively small sizes compared to those distances, it's practically impossible to create a visual representation on a screen or the page of a book that realistically represents the sizes of the planets and the distance between them.
