Suppose a student develops a scale model of the planets. Which two planets should be the closest in diameter on the model?

Answer 1

On a scale model of the planets, the two closest planets in terms of diameter would be Earth and Venus.

The diameter of Earth is approximately 12,742 kilometers, while the diameter of Venus is approximately 12,104 kilometers. These values are relatively close, making Earth and Venus the best options to be the closest in diameter on a scale model.
