How far out does space start?
100 kilometers
A common definition of space is known as the Kármán Line, an imaginary boundary 100 kilometers (62 miles) above mean sea level. In theory, once this 100 km line is crossed, the atmosphere becomes too thin to provide enough lift for conventional aircraft to maintain flight.
How far is ground level from space?
about 62 miles
There’s also fuel problem too. The shortest distance between Earth and space is about 62 miles (100 kilometers) straight up, which by general accord is where the planet’s boundary ends and suborbital space begins.
How high up is space in Ft?
The Kármán line is the altitude of the boundary between earth’s atmosphere and outer space. This 100 km or 328, 084 ft. The value comes from Fédération Aéronautique Internationale, and it’s the same value that NASA uses to define the boundary between our planet’s atmosphere and outer space.
Where is the highest gravity on Earth?
Free fall favourite Mount Nevado Huascarán in Peru has the lowest gravitational acceleration, at 9.7639 m/s2, while the highest is at the surface of the Arctic Ocean, at 9.8337 m/s2.
What is earth’s gravity?
9.807 m/s²

What happens if astronaut floats away?
The astronaut would probably end up trapped in orbit around the Earth, far away from the International Space Station, until their oxygen supply ran out, or until the space suit gets a tear in it from space junk.
How tall is the average height of space?
In the US, “space” begins at 80.4km (50 miles), or 264,000 feet. General international consensus sets a similar limit for the start of space as 100km (62 miles), or 380,000 feet.
Where does space start in relation to Earth?
Credit: NOAA The U.S. military and NASA define space differently. According to them, space starts 12 miles below the KaÌrmaÌn Line, at 50 miles above Earth’s surface. Pilots, mission specialists and civilians who cross this boundary are officially deemed astronauts.
How tall is the International Space Station in miles?
The International Space Station (ISS) cruises higher up, from 278km (173 miles, 912,000 feet) to 460km (286 miles, 1.5 million feet). Starting above the ‘space’ limit but a bit before LEO, the inner Van Allen Belts, which magnetically shield the Earth’s surface from high energy particles, extend from 100km (62 miles, 33,000 feet) up to 10,000km
How tall can a plane fly in space?
Military jets (from the SR-71 onward to modern planes) can hit over 30km (19 miles) up, over 100,000 feet. Can you parachute from that height?
