How does the iss move in space?

Answer 1

its gravitationally bound to the earth,i.e it orbits earth.just like the moon. it orbits once every 90mins or so

>

In a circle and unpowered

(At stable orbit) Gravity = Centripetal force

Essentially, for any given orbital radius, only one velocity will keep it in stable orbit.

1. Select orbit radius (r)

2. Calculate required velocity (v) from: v = square root (G * m) / r

(G = Newtons gravitational constant, m = earths mass)

3. Calculate (sidereal) orbit time from (2 * pi * r) / v

Answer 2

The International Space Station (ISS) moves through space by constantly orbiting Earth. It travels at a speed of about 28,000 kilometers per hour, completing an orbit around Earth approximately every 90 minutes. This speed allows it to maintain a stable orbit in space while continuously falling towards Earth due to gravity but moving forward at a sufficient speed to stay in orbit.
