When will the International Space Station pass over Tehran?

ISS stands for the International Space Station — the largest and brightest human-made object in orbit around Earth. Passes over Tehran above 10° in the next 10 days: 43. Of those, visible to the naked eye: 5.

The next pass of the International Space Station over Tehran is on Tuesday 25 Aug at 02:32 local time, reaching 21° above the horizon. The next pass you can actually see is on Sunday 30 Aug at 05:04 (12° above the horizon).

How to spot it

Look for a bright, fast “star” that doesn't blink — the ISS outshines everything except the Moon and Venus.
It moves west to east, crossing the whole sky in 3–6 minutes.
Evening and pre-dawn passes are the visible ones — the station must be sunlit while your sky is dark. Daytime passes in the table are invisible to the eye.
Tehran sits within the ISS's orbital band, so it can pass nearly straight overhead — those 70°+ passes are spectacular.
