I've confirmed that description #5 asks for "The coldest planet in the solar system." Based on astronomical data, Neptune is generally considered the coldest planet in our solar system, with average temperatures around -214°C (-353°F). While Uranus can sometimes be colder at its poles, Neptune has the lowest recorded temperature of any planet.
Now I'll provide the complete solution to the worksheet.
Solution:
1. The largest planet in the solar system. →
