## Step 1<br />The problem is about the orbital speed of Mars. The orbital speed of a planet is the speed at which it orbits the Sun. This speed is not constant, but varies depending on the planet's distance from the Sun.<br /><br />## Step 2<br />The first statement, "Mars's orbital speed is constant, regardless of its distance from the Sun", is incorrect. This is because the orbital speed of a planet varies depending on its distance from the Sun. This is due to Kepler's second law, which states that a planet's speed increases as it gets closer to the Sun and decreases as it moves away.<br /><br />## Step 3<br />The second statement, "Mars's speeds up when it is closest to the Sun (perihelion)", is correct. This is because, according to Kepler's second law, a planet's speed increases as it gets closer to the Sun.<br /><br />## Step 4<br />The third statement, "Mars's moves slower when it is farthest from the Sun (aphelion)", is also correct. This is because, according to Kepler's second law, a planet's speed decreases as it moves away from the Sun.<br /><br />## Step 5<br />The fourth statement, "Mars's orbital speed fluctuates more than Earth's because of its higher eccentricity", is correct. This is because Mars has a higher eccentricity than Earth, which means its orbit is more elongated. This causes Mars's speed to fluctuate more than Earth's.
