International Space Station Orbit Distance and Altitude

The International Space Station (ISS) orbits the Earth at an altitude of approximately 400 kilometers (km) above the planet's surface, placing it in low Earth orbit (LEO) Neubert2023Badhwar2001Calle2016+2 MORE. Some sources specify the altitude as about 370 km, but the most commonly cited and current operational altitude is around 400 km Ticker2009Neubert2023Badhwar2001+3 MORE. This altitude allows the ISS to circle the Earth roughly every 90 minutes.

Orbit Inclination and Coverage

The ISS travels in an orbit with an inclination of 51.6 degrees. This means its path is tilted relative to the equator, allowing it to pass over a wide range of latitudes and cover about 90% of the Earth's population and surface features Ticker2009Neubert2023Badhwar2001+2 MORE. The combination of its altitude and inclination enables the ISS to observe both low- and mid-latitude regions, making it an ideal platform for scientific research and Earth observation Neubert2023Warren2020.

Distance from Earth and Research Benefits

At an altitude of 400 km (about 250 miles), the ISS is much closer to Earth than satellites in geostationary orbit, which are about 36,000 km away. This proximity allows for high-resolution observations of the Earth's surface and atmosphere, as well as easier access for resupply missions and crew rotations Neubert2023Warren2020. The ISS's low orbit also exposes it to unique environmental conditions, such as microgravity and increased radiation, which are valuable for scientific experiments Warren2020Serpolla2023.

Conclusion

In summary, the International Space Station orbits the Earth at a distance of about 400 km above the surface, with a 51.6-degree inclination. This orbit provides broad coverage of the planet, supports a wide range of scientific research, and offers unique opportunities for studying both space and Earth from a close vantage point Ticker2009Neubert2023Badhwar2001+4 MORE.
