A satellite orbits the sun with a period of 2.00 days. What is the radius of its orbit. Express your answer with the appropriate units.

To determine the radius of the satellite's orbit around the Sun, we can use **Kepler's Third Law of Planetary Motion**, which states:

\[
T^2 = \frac{4\pi^2}{G M_{\text{sun}}} r^3
\]

Where:
- \(T\) is the orbital period (2.00 days),
- \(r\) is the orbital radius,
- \(G\) is the gravitational constant (\(6.67430 \times 10^{-11} \, \text{m}^3/\text{kg}\cdot\text{s}^2\)),
- \(M_{\text{sun}}\) is the mass of the Sun (\(1.989 \times 10^{30} \, \text{kg}\)).

### Step 1: Convert the period \(T\) to seconds
Since the period is given in days, we need to convert it to seconds:
\[
T = 2.00 \, \text{days} \times 24 \times 60 \times 60 = 172800 \, \text{seconds}
\]

### Step 2: Rearrange Kepler's Third Law to solve for \(r\)
\[
r^3 = \frac{G M_{\text{sun}} T^2}{4\pi^2}
\]

### Step 3: Plug in the known values
\[
r^3 = \frac{(6.67430 \times 10^{-11}) (1.989 \times 10^{30}) (172800)^2}{4\pi^2}
\]

### Step 4: Solve for \(r\)
First, compute the right-hand side and then take the cube root.

\[
r^3 = 1.18 \times 10^{35} \, \text{m}^3
\]
\[
r = \sqrt[3]{1.18 \times 10^{35}} = 4.91 \times 10^{11} \, \text{m}
\]

Thus, the radius of the satellite's orbit is approximately:

\[
r \approx 4.91 \times 10^{11} \, \text{m}
\]

### Final Answer:
\[
r \approx 4.91 \times 10^{11} \, \text{m}
\]
