To determine which two planets should be the closest in diameter in a scale model, we can compare the diameters of the planets listed:

  • Mercury: 4,800 km
  • Venus: 12,100 km
  • Earth: 12,800 km
  • Mars: 6,700 km
  • Jupiter: 143,000 km
  • Saturn: 120,000 km
  • Uranus: 51,100 km
  • Neptune: 50,000 km

From this comparison, the diameters of Uranus (51,100 km) and Neptune (50,000 km) are the closest in size, with only a 1,100 km difference.

Therefore, the response would be:

Uranus and Neptune
