When will the International Space Station pass over Cambridge?

ISS stands for the International Space Station — the largest and brightest human-made object in orbit around Earth. Passes over Cambridge above 10° in the next 10 days: 44. Of those, visible to the naked eye: 18.

The next pass of the International Space Station over Cambridge is on Saturday 12 Sept at 20:10 local time, reaching 29° above the horizon. That is also the next one you can see with the naked eye.

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. 2 good windows in the next 3 days (marked ★).
Cambridge is outside the ISS's ±51.6° orbital band, so it always appears toward the horizon rather than overhead.
