## Why does the International Space Station travel so fast?

Because the rockets that launched the components of the ISS started on a rotating surface (the Earth), the speed of that rotation is added to the speed the ISS travels in its orbit, meaning we didn’t have to burn as much fuel to get to 17,500 mph (28,000 km/h).

### How far is the International Space Station from Earth?

408 km
International Space Station/Orbit height

The space station is made of parts that were assembled in space by astronauts. It orbits Earth at an average altitude of approximately 250 miles. It travels at 17,500 mph. This means it orbits Earth every 90 minutes.

#### How long is the trip from the space station to Earth?

roughly 93 minutes
The ISS circles the Earth in roughly 93 minutes, completing 15.5 orbits per day.

What is the longest a person has ever been in space without coming back to Earth?

Before Vande Hei’s long stay in space, the longest spaceflight by an American was held by Scott Kelly, who spent 340 days at the ISS in 2015–16. However. Russian cosmonaut Valeri Polyakov spent 437 days on the Mir space station from 1994 and 1995 still holds the record for the longest time a person has stayed in space.

How many miles high is the space station?

It orbits at approximately 220 miles (350 km) above the Earth and it travels at an average speed of 17,227 miles (27,724 km) per hour.

## How many miles is the space station?

The International Space Station maintains an orbit approximately 250 miles (400 kilometers) above sea level, while the Hubble Space Telescope operates at an altitude of about 340 miles (550 kilometers).

### How does the International Space Station travel around the Earth?

That’s what the ISS does. The ISS revolves around the Earth at about 17,500 mph (~28,000 km/h) resulting in it completing one revolution in about 90 minutes, and about 16 revolutions per day.

#### How long does it take for the ISS to orbit the Earth?

The ISS revolves around the Earth at about 17,500 mph (~28,000 km/h) resulting in it completing one revolution in about 90 minutes, and about 16 revolutions per day. The ISS rotates about its center of mass at a rate of about 4 degrees per minute so that it will complete a full rotation once per orbit.

Is it possible to catch the International Space Station?

Despite being relatively close, the ISS is traveling at more than 17,000 miles per hour in a circular orbit around Earth. Anything moving that fast, whether in space or on the ground, is going to be hard to catch. As it turns out, the way you catch the ISS is counterintuitive: You actually let it catch you.

How often does the International Space Station disappear in the night sky?

Disappears represents where in the night sky the International Space Station will leave your field of view. How fast is the space station travelling? The ISS circles the Earth every 90 minutes.
