Planet sizes and spacing need different scales
A diagram that shows planets clearly usually cannot show their real separation at the same scale.
Light-time makes distance intuitive
Sunlight takes a little over eight minutes to reach Earth.
Outer planets are much farther apart
Travel times and orbital periods increase strongly with distance.
Scale changes intuition
Space is mostly empty compared with the sizes of planets and stars.
