The International Space Station
Did you know the International Space Station was first inhabited by astronauts on November 2, 2000? That is 4383 days of continuous occupation! The Space Station completes 15.7 orbits in one day, which means since its first part was launched into orbit in 1998, it has made nearly 80000 orbits.
The Space Station is not owned by any one country but rather it is a collaborative project between 15 nations "to design, assemble, occupy, and conduct research inside and outside of the largest and longest inhabited object to ever orbit the Earth."
