International Space Station
The International Space Station is a large habitable satellite that orbits Earth and serves as a research laboratory.
How big is it?
28,160 km/h
Also 17,500 mph
Speed · approximate
A little perspective
About 1.15 times the orbital speed of Uranus.
Uranus: Uranus is an ice giant planet with a blue-green atmosphere, orbiting the Sun on its side.
Measurements, assumptions & sources +
International Space Station
NASA’s rounded 17,500 mph orbital-speed figure. This is motion around Earth, not speed relative to an astronaut inside.
NASA — International Space Station
The marked speed is calibrated. Unmeasured illustration details are representative.
Uranus
Mean-radius spherical model for Uranus; actual shape is not perfectly spherical. Gravity refers to a conventional atmospheric level, not solid ground.
Rounded representative orbital speed, not instantaneous ephemeris data.
Defined examples — our methodology
The marked orbital speed is calibrated. Unmeasured illustration details are representative.
