How High Is Outer Space

Distance in outer space are so vast that terrestrial units of measurement lose their meaning so astrophysicists have devised more useful ones.

How high is outer space. Mesosphere of earth s atmosphere. They use the astronomical unit which is 149 597 870. Outer space does not begin at a definite altitude above the earth s surface.

The boundary between earth and outer space at 328 084 ft is roughly 11 times higher than mt. By the same token space is often defined as beginning at the lowest altitude at which satellites can maintain orbits for a reasonable time which is approximately 160 kilometers 100 miles above. The kármán line an altitude of 100 km 62 mi above sea level is conventionally used as the start of outer space in space treaties and for aerospace records.

First that it seems the internationally accepted standard for defining where outer space actually begins is the kármán line at an altitude of 100 km 62 mi above sea level and that we have agreed on certain treaties namely the outer space treaty based on this definition. Mesosphere the mesosphere starts just above the stratosphere and extends to 85 kilometers 53 miles high. The line owes its name to theodore von karman a hungarian american physicist who was the first to determine that around this altitude the atmosphere became too thin to support aeronautical flights.

Meteors burn up in this layer thermosphere. Space starts here at 100 kilometers the view from here. Try to picture that for a moment.

Bill nye teams up with 4 h to take students to mars space is part of future us inc an international media group and. The stratosphere starts just above the troposphere and extends to 50 kilometers 31 miles high. The ozone layer which absorbs and scatters the solar ultraviolet radiation is in this layer.

The outer space treaty is born. Everest as well as the highest up you ve probably ever been. On this day in space.
