The boundary between Earth's atmosphere and outer space is not definitively defined, but a commonly accepted boundary is the Kármán line, which is located at an altitude of 100 kilometers (62 miles) above sea level. Below this altitude, the atmosphere is dense enough that aerodynamic lift is possible for aircraft. Above the Kármán line, the atmosphere becomes too thin for conventional aircraft to achieve sustained flight, marking the transition to outer space.
However, the atmosphere itself gradually thins as altitude increases, and its effects can be felt at much higher altitudes than the Kármán line, with traces of atmospheric particles extending well into the thermosphere, which reaches up to about 600 kilometers (372 miles) above the Earth.
