The period of revolution of planet A around the sun is 8 times that of \( B \). The distance of \( A \) from the sun is how many times greater than that of \( B \) from the sun?
Show Hint
- Kepler’s Third Law: $T^2 \propto r^3$
- Larger time period $\Rightarrow$ planet is farther from the sun
- Always square the time ratio, then take cube root to find distance ratio
