Assume a Textbook Shows a Diagram of the Solar System

Essay

Assume a textbook shows a diagram of the solar system on, say, a standard notebook-sized sheet. The orbits of eight planets are sketched around the sun at the center. Disks on each orbit are large enough to show features like continents on Earth or the rings of Saturn. There is a similar-sized disk for the sun with some sunspots. Discuss what is wrong or right with this diagram.
