To calculate the weight of a 1,413 kg rover on the surface of Earth's moon, we use the following formula:

\[
W = m \times g_{\text{moon}}
\]

Where:
- \( W \) is the weight (in newtons, N).
- \( m \) is the mass of the rover (1,413 kg).
- \( g_{\text{moon}} \) is the gravitational acceleration on the moon, which is approximately \( 1.625 \, \text{m/s}^2 \).

### Step 1: Calculate the weight in newtons (N)
\[
W = 1,413 \, \text{kg} \times 1.625 \, \text{m/s}^2 = 2,294.625 \, \text{N}
\]

### Step 2: Convert to kilonewtons (kN)
Since \( 1 \, \text{kN} = 1,000 \, \text{N} \):
\[
W = \frac{2,294.625 \, \text{N}}{1,000} = 2.294625 \, \text{kN}
\]

### Step 3: Round to three significant digits
The weight in kilonewtons, rounded to three significant digits, is:
\[
W \approx 2.29 \, \text{kN}
\]

Thus, the weight of the 1,413 kg rover on the moon is **2.29 kN**.
