How Many Miles Is It To Space

In the us space begins at 80 4km 50 miles or 264 000 feet.

How many miles is it to space. The number of miles required to reach outer space depends on whom is asked. According to data collected by the university of calgary space begins and the earth s atmosphere ends at 73 miles above the earth s surface. America tends to use 50 miles as their definition for things like awarding people their astronaut wings.

The space industry lists 62 miles. Low earth orbit leo where many satellites live goes from 160km 100 miles 525 000 feet to 2 000km 1 240 miles 6 5 million feet. The most widely accepted boundary is the so called karman line nowadays usually set to be 62 miles altitude here s the problem.

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. Others place the marker at an astronomical 13 million miles. According to mcdowell that karman line that many scientists.

General international consensus sets a similar limit for the start of space as 100km 62 miles or 380 000 feet. Nasa s web site will check the telemetry from the space station and gather its exact latitude and longitude as it orbits about 200 miles over the earth traveling 17 500 miles an hour making one full orbit every hour and a half. The internationally agreed boundary of space is 100km or 62 miles.

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.
