According to Kepler's laws, the period of a planet's orbit depends on the planet's distance from the Sun and the mass of the Sun. Since Jupiter is much more massive than Earth and orbits at a greater distance from the Sun, it requires a greater velocity to maintain its orbit. Thus, the minimal orbit speed about Jupiter is greater than 8 km/s. Therefore, the correct answer is B.

Minimal Orbit Speed About Earth Is About 8 Km/s, and About
