To determine the two planets that should be the closest in diameter on the scale model, we need to compare their diameters.
Looking at the given list of planet diameters:
Mercury: 4,800
Venus: 12,100
Earth: 12,800
Mars: 6,700
Jupiter: 143,000
Saturn: 120,000
Uranus: 51,100
Neptune: 50,000
Based on the given diameters, the two planets that should be closest in diameter on the model are:
- Uranus (51,100 km) and Neptune (50,000 km)
Therefore, the correct answer is "Uranus and Neptune."
