To determine which two planets should be the closest in diameter based on the provided data, let's compare the diameters of each pair:

  • 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

Now, let's compare the possible pairs from the options given:

  1. Earth and Venus:

    • Earth: 12,800 km
    • Venus: 12,100 km
    • Difference: 700 km

  2. Mars and Jupiter:

    • Mars: 6,700 km
    • Jupiter: 143,000 km
    • Difference: 136,300 km

  3. Mercury and Neptune:

    • Mercury: 4,800 km
    • Neptune: 50,000 km
    • Difference: 45,200 km

  4. Uranus and Saturn:

    • Uranus: 51,100 km
    • Saturn: 120,000 km
    • Difference: 68,900 km

Based on these comparisons, the closest diameters are those of Earth and Venus with a difference of 700 km.

So, the correct answer is:

Earth and Venus.
