Research reveals more than 700 satellites above a typical UK town at night

New research from precision engineering supplier Accu Components has revealed that approximately 710 satellites are visible in the sky above a typical UK town at any moment after dark, with 12,891 different satellites passing overhead during a single night.

The study tracked 15,883 active low Earth orbit satellites across 186 UK towns and cities over seven nights in October 2026, monitoring their positions every two minutes.

The findings highlight the rapid growth of satellite networks, with 20,095 satellites now in orbit, almost four times the number recorded at the end of 2019. Around 70 per cent of active low Earth orbit satellites belong to SpaceX's Starlink, with further expansion expected from Amazon Leo and China's Guowang and Qianfan networks.

The research also found significant regional differences. Plymouth recorded the highest number of satellites high overhead at any moment after dark, with 83, followed by Southampton, Brighton, Bristol and Cardiff with 82 each. London recorded 81.

However, northern Scotland offers some of the best opportunities for spotting satellites, with Lerwick recording 125 satellites catching sunlight at any moment after dark.

The growing number of satellites also raises concerns about orbital congestion and space debris. Accu Components warned that collisions could create further debris, potentially triggering a chain reaction known as Kessler syndrome, which could make certain orbital regions increasingly hazardous.

The findings underline the growing importance of satellite infrastructure while highlighting the challenges associated with managing an increasingly crowded low Earth orbit.
