Question
**Understanding the Angular Diameter of Saturn**

When studying the angular diameter of Saturn as observed from Earth, it is important to use the small-angle formula. This formula relates the linear diameter of an object to its angular diameter and distance from the observer.

### Angular Diameter Calculation

**Formula:**
\[ \text{angular diameter (in arc seconds)} = \left( \frac{\text{linear diameter}}{\text{distance}} \right) \times 2.06 \times 10^5 \]

### Questions:

1. **Closest Approach:**
   - Calculate the angular diameter of Saturn (in arc seconds) when Earth and Saturn are closest together.
   - Enter the value in the provided box.

   \[ \_\_\_\_\_ \text{ arc seconds} \]

2. **Farthest Distance:**
   - Calculate the angular diameter of Saturn (in arc seconds) when Earth and Saturn are farthest apart.
   - Enter the value in the provided box.

   \[ \_\_\_\_\_ \text{ arc seconds} \] 

Use these calculations to understand how the apparent size of Saturn changes based on its distance from Earth.
