How to find the orbital radius of a planet?

To find the orbital radius of a planet, you would need to gather and use certain information. Here is a step-by-step explanation:

1. Identify the planet: Determine which planet you want to find the orbital radius for. Let's assume it's Earth for this example.

2. Collect necessary data: Obtain the necessary data for the planet, including its mass (M) and the period of its orbit (T).

3. Find the gravitational constant: The gravitational constant (G) is a fundamental constant of nature and its value is approximately 6.67430 x 10^-11 m^3 kg^-1 s^-2.

4. Calculate the orbital radius: Use the following formula to determine the orbital radius (r) of the planet:

r = [(G * M * T^2) / (4 * π^2)]^(1/3)

In this formula, "π" represents the mathematical constant Pi.

5. Substitute values and calculate: Plug in the values of the gravitational constant (G), the mass of the planet (M), and the period of the orbit (T) into the formula and calculate the orbital radius (r).

6. Units: Ensure that the units used in the formula are consistent. For example, if the mass (M) is in kilograms (kg), the orbital radius (r) will be in meters (m), and the period (T) will be in seconds (s).

By following these steps and using the given data, you can find the orbital radius of a planet. Remember to double-check your calculations and unit conversions to ensure accuracy.
