Minimal orbit speed about Earth is about 8 km/s. Minimal orbital speed about Jupiter would be
A)less than 8 km/s.
B)more than 8 km/s.
C)about 8 km/s.

Question

Quizplus · Accepted Answer

The minimal orbital speed about a planet is determined by the planet's mass and radius. Since Jupiter has a much larger mass and radius than Earth, its gravitational pull is stronger and the minimum speed required to maintain an orbit around it is higher than the minimal speed required to orbit Earth. Thus, the minimal orbital speed about Jupiter is more than 8 km/s.

Minimal Orbit Speed About Earth Is About 8 Km/s
