What is the diameter of Milky way?

Options

A. 1000 light year
B. 10000 light year
C. 100000 light year
D. 100000 km

Explanation

**Step-by-Step Solution:**

1. **Understanding the Milky Way**: The Milky Way is a galaxy that contains our solar system, including Earth. It appears as a band of light in the night sky, which is made up of countless stars.

2. **Identifying the Radius**: The radius of the Milky Way galaxy is approximately 52,800 light years. This means that from the center of the galaxy to its edge, it spans this distance.

3. **Calculating the Diameter**: The diameter of a circle (or in this case, a galaxy) is twice the radius. Therefore, to find the diameter of the Milky Way, we will multiply the radius by 2.
- Diameter = 2 × Radius
- Diameter = 2 × 52,800 light years

4. **Performing the Calculation**:
- Diameter = 105,600 light years

5. **Rounding the Result**: For simplicity and based on common approximations, we can round this figure to approximately 100,000 light years when discussing the size of the Milky Way.

6. **Final Answer**: Therefore, the diameter of the Milky Way is approximately 100,000 light years.
