The largest human-made structure in space is the International Space Station (ISS). The ISS is a modular space station that orbits Earth and serves as a microgravity and space environment research laboratory. It was assembled in low Earth orbit, with various modules and components launched and connected over time.
The ISS has a mass of around 420,000 kilograms (approximately 925,000 pounds) and measures about 109 meters (358 feet) end-to-end, which is roughly the size of a football field, including the end zones. It accommodates astronauts from various countries and has been continuously inhabited since November 2000. The ISS plays a crucial role in scientific research, technology development, and international cooperation in space exploration.
