What is the maximum possible distance that can be drawn between Mars an Neptune in the scale model

To calculate the maximum possible distance between Mars and Neptune in a scale model, we need to know the scale of the model. Scale represents the proportion between the model and the actual object.

Let's assume the scale model of the solar system is 1:1 billion, meaning every one unit in the model represents one billion units in reality.

In reality, the average distance between Mars and Neptune is approximately 3.03 billion miles (4.88 billion kilometers).

To find the maximum distance in the scale model, we simply multiply the actual distance by the scale. Therefore, the maximum possible distance between Mars and Neptune in the scale model would be:

3.03 billion miles * 1 billion = 3.03 billion billion miles

Please note that "billion billion" refers to 10^18, known as a quintillion or one trillion trillion.
