Most of the time, the International Space Station (ISS) is orbiting the Earth at an altitude of approximately 220 miles (354 km), which places it in low Earth orbit (LEO). This distance can change, however, and has varied from 205 miles (330 km) to a planned maximum of 248 miles (400 km).
Even though our International Space Station is in a Low-earth orbit, It's at an altitude of about 350-400 kms (which lies in the exosphere). In order to overcome the orbital velocity, one needs some special thrusters in addition to their pressurized spacesuit.s other answers say, if someone just jumps off of the international space station(ISS), they would still be in orbit around the earth since the ISS is traveling at 17,000 miles per hour (at an altitude of 258 miles).
