The O2 Arena from Space: Too Small to See with Naked Eye

The O2 Arena (formerly Millennium Dome) in Greenwich, London, cannot be seen from space with the naked eye. At 365 meters diameter and 55 meters high, it falls below the resolution threshold for human vision from low Earth orbit (~150–400 km), where objects under ~50–100 meters are indistinguishable. While satellites with high-resolution sensors can image it, astronauts cannot resolve it visually. Its fame comes from hosting 2 million annual visitors as a premier entertainment venue, not orbital visibility. The myth likely confuses it with larger human-made features like cities or highways.
