Answer 1

To estimate the average distance of Uranus from the Sun, we can look at the distances of Saturn and Neptune from the Sun, which are given in the table:

• Saturn: 9.5 AU
• Neptune: 30 AU

Since Uranus is between these two planets, a reasonable estimate would be the average of these two distances.

Calculating the average: \[ \text{Average distance} = \frac{9.5 + 30}{2} = \frac{39.5}{2} = 19.75 \text{ AU} \]

This rounds to approximately 20 AU.

Therefore, the most reasonable estimate for the distance of Uranus from the Sun is 20 AU.
