The mean distance of Mars from the Sun is 1.52 times that of Earth from the Sun. From Kepler's law of periods, calculate the number of years required for Mars to make one revolution around the Sun, compare your answer with the value given in Appendix C.

Explanation

To solve the problem, we will use Kepler's Third Law of Planetary Motion, which states that the square of the orbital period (T) of a planet is directly proportional to the cube of the semi-major axis of its orbit (R). This can be expressed mathematically as:

\[ T^2 \propto R^3 \]

### Step-by-Step Solution:

1. **Identify the relationship using Kepler's Law**:
According to Kepler's law, we can write the relationship for Mars and Earth as follows:
