How Many Miles Away Is Space

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.

How many miles away is space. Voyager 1 was launched in 1977. As of 2015 it is over 12 161 300 000 miles away from earth. By 1989 it had visited jupiter and saturn and crossed the orbits of but did not visit uranus and neptune. The framework for international space law was established by the outer space treaty which entered into force on 10 october 1967.

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. The number of miles required to reach outer space depends on whom is asked. However other countries and agencies have a differing opinion on where space begins. Others place the marker at an astronomical 13 million miles.

Beyond our own galaxy lies a vast expanse of galaxies. The space industry lists 62 miles. The deeper we see into space the more galaxies we discover. In the summer of 2012 a nasa spacecraft named voyager 1 became the first human made object to enter interstellar space.

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 keeping. Nasa sets the boundary at 76 miles. Beyond a certain specific distance calculated by me to be approximately 18 billion light years away at present even a signal moving at the speed of light will never reach us. This distance can change however and has varied from 205 miles 330 km to a planned maximum of 248 miles 400 km.
