How high is space from the earth?

Answer 1

Average orbit, 340 kilometers, or 210 miles.

It drops about 2.5 kilometers (1.5 miles) per month, so every time the Space Shuttle links up with it, the Shuttle boosts it up about 10 miles or so.

this will not help any one becase its wrong

Answer 2

The boundary commonly recognized as the beginning of space is called the Kármán line, which is located at an altitude of 100 kilometers (62 miles) above sea level. This is where the Earth's atmosphere becomes too thin to support conventional aircraft flight.

Answer 3

The distance from Earth to the Internatonal Space Station (ISS) is only a tiny fraction of the distance from Earth to Moon. The ISS is maintained at an orbit with a minimum altitude of 278 km to a maximum of 460 km. The distance from the Earth to the Moon ranges from 356,400 km to 406,700 km.

Answer 4

Scientists believe that beyond our known galaxy, that other galaxies exist that are even larger than ours. Obviously, we don't know the exact size of space, but as others noted, scientists suspect it may be infinite.

Answer 5

Depends what you call "space". You might say that space starts where Earth's atmosphere ends. Earth's atmosphere doesn't end abruptly, but after a few hundred km., there is not much atmosphere to speak of.

Answer 6

That depends on the purpose of the photograph. If you are photographing weather patterns, the satellite needs to be pretty high to get a wide-area picture. Weather satellites are often in geosynchronous orbit at 23,000 miles high.

If you are photographing things and people on the Earth, you want to be as low as possible in order to get a good photo. The lowest you can go and maintain a stable orbit would be about 120 miles; any lower, and the drag of the atmosphere will eventually bring the satellite down.

Answer 7

The International Space Station orbits at an altitude of about 150 miles. Future space stations will likely be positioned in geosynchronous orbits at about 23,000 miles up, or in the Lagrangian points of the Earth-Moon system, about 250,000 miles from Earth.

Answer 8

The international Space Station orbits the Earth once every 90 minutes or so. There's a NASA web site that will show you the current position of the ISS (and more than a thousand other satellites). And spaceweather.com has a link to an overflights calculator that will show you when the ISS will be visible in the pre-dawn or evening sky from your location.

Answer 10

There is no clear boundary, but the 100km Kármán line (62 miles up) is generally regarded as the boundary of outer space. Here, a vehicle would have to travel faster than its orbital velocity to gain sufficient lift from the few molecules of air at this height.

The United States designates people who travel above an altitude of 80km (50 miles) as astronauts.
