Can you see the ISS from Denver?

The International Space Station is visible from Denver several times a month, whenever it passes overhead during the hour or two after sunset or before sunrise while it is still catching sunlight against a dark sky. No telescope is needed; the station is one of the brightest objects in the night sky and is easily seen with the unaided eye.

About the International Space Station

The International Space Station is the largest human-made structure in orbit, about the size of a football pitch and weighing roughly 420 tonnes. It circles the Earth at an altitude of around 420 kilometres and a speed of about 28,000 kilometres per hour, completing one orbit roughly every 90 minutes. That means the crew on board see around 16 sunrises and sunsets every day.

Because the station is so large and its solar panels are so reflective, it shines by reflected sunlight and can become one of the brightest objects in the night sky. It is visible from the ground without any equipment whenever it passes overhead during twilight, when the observer is in darkness but the station high above is still bathed in sunlight.

How to spot the ISS from Denver

Find a spot with a clear view of the sky and as little light pollution as possible. A few minutes before the pass time listed above, look towards the rising direction shown for the pass. You do not need a telescope or binoculars; the station is easily bright enough to see with your eyes alone.

The ISS appears as a steady, bright point of light that glides smoothly across the sky. Unlike an aircraft it has no flashing or coloured lights. A pass lasts only a few minutes, and the station may suddenly fade and disappear partway across the sky as it crosses into the Earth’s shadow, so be ready and keep watching.
