If the Earth were a volley ball what would be the diameter of the Sun? What object matches this size?

Answer

The diameter of the Earth is $2 * 6400 \, \text{km} = 1.28 * 10^{7} \, \text{m}$.

The diameter of the Sun is $2 * 695500 \, \text{km} = 1.391 * 10^{9} \, \text{m}$.

The diameter of a volley ball is around $20 \, \text{cm} = 0.2 \, \text{m}$.

$$\frac{d_{\text{ball}}}{x} = \frac{d_{\text{Earth}}}{d_{\text{Sun}}} \rightarrow x = \frac{d_{\text{ball}} * d_{\text{Sun}}}{d_{\text{Earth}}} \approx 22 \, \text{m}$$

If the Earth were a volley ball, the Sun’s diameter would be 22 m. It is around the height of -5 storeys building.
