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



Comparison of Planet Size

Planet Diameter (km)
Mercury 4,800
Venus 12,100
Earth 12,800
Mars 6,700
Jupiter 143,000
Saturn 120,000
Uranus 51,100
Neptune 50,000
A:Uranus and Saturn
B:Mars and Jupiter
C:Mecury and Neptune
D:Earth and venus

The correct answer is C: Mercury and Neptune. According to the given information, the diameter of Mercury is 4,800 km and the diameter of Neptune is 50,000 km. These two planets have the closest diameters, making them the closest on the scale model.
