FAQ

How do I recognise the ISS in the sky?

It looks like a very bright star that does not twinkle and moves smoothly across the sky, usually from west to east. A pass lasts a few minutes. Planes have blinking lights, the ISS shines with a steady white light.

Why can I see the ISS only in the morning and evening?

The station does not shine by itself, it reflects sunlight. You see it when it is already dark where you are, while the station about 400 km up is still lit by the Sun. That usually happens within 1-2 hours after sunset or before sunrise.

How fast does the ISS travel?

About 28,000 km/h. One orbit of the Earth takes about 90 minutes, so it circles the planet more than 15 times a day.

How do you know where the station is?

We calculate its position live in your browser from orbital data (TLE) published by CelesTrak. The data is refreshed several times a day, so the position is accurate to a few kilometres.
