How fast does the ISS travel?

The International Space Station travels at approximately 28,000 km/h (17,500 mph), completing one orbit around Earth every 90 minutes. This means it circles our planet about 16 times per day!

When can I see the ISS from my location?

The ISS is visible when it passes over your location during twilight hours (just after sunset or before sunrise) when the sky is dark but the station is still illuminated by the Sun. Our tracker calculates these optimal viewing times for your specific location.

How high is the ISS orbit?

The ISS orbits at an altitude of approximately 400-420 km (250-260 miles) above Earth's surface. This altitude is known as Low Earth Orbit (LEO).

What does the ISS look like when visible?

When visible, the ISS appears as a bright, steady light moving across the sky (unlike twinkling stars or flashing aircraft). It's often the third brightest object in the night sky after the Moon and Venus, and takes 2-5 minutes to cross the visible sky.

Is this ISS tracker free to use?

Yes! This ISS tracker is completely free to use with no subscriptions, accounts, or hidden fees. FreeWWW.com provides free tools and utilities for everyone.
