ISS

International Space Station is a low Earth orbit habitable artificial satellite project, started by the space agencies of USA, Russia, Europe, Japan, Canada, Brazil and Italy, back in 1998.

ISS orbit

ISS may be observed with a naked eye, moving at low Earth orbit with an altitude between 330 km and 435 km, orbital inclination of ∠51.65° and an average orbital speed of 27 600 km/h (17 100 mph). Every day the space station loses about 100 m of its altitude because of atmospheric resistance, that is why orbital corrections are made often.
