How fast does the ISS have to travel to remain in a stable orbit a few hundred km above the Earth?
About 1,600 km/hr, the same speed as the Earth's surface.
About 3,600 km/hr, the same speed the Moon travels around the Earth.
Around 5,400 km/hr, the speed of the fastest bullet on Earth.
Around 10,000 km/hr, because it's a big, round number.
Much more than any of these paltry choices.
