The International Space Station (ISS) is a modular space station in low Earth orbit. Low Earth orbit is an Earth-centred orbit with an altitude of 2,000 km (1,200 mi) or less, or with at least 11.25 periods per day (an orbital period of 128 minutes or less) and an eccentricity less than 0.25.).[1]https://en.wikipedia.org/wiki/Low_Earth_orbit
ISS is the largest artificial object in space and the largest satellite in low Earth orbit. Depending on your location on the Earth’s surface, the spacecraft’s position in orbit and the time of day, you may be able to see the ISS as it orbits about 386 kilometers (240 miles) above the planet. A spacecraft will be seen as a steady white pinpoint of light moving slowly across the sky. [2]https://spaceflight.nasa.gov/realdata/sightings/help.html.
The ISS circles the Earth in roughly 93 minutes, completing 15.5 orbits per day. You can check the sightseeing opportunities real-time at NASA HumanSpaceFight website. [3]https://spaceflight.nasa.gov/realdata/tracking/index.html
