Question: Where Does Space Start?

Where does space start in feet?

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.

“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)..

How far from Earth is space?

about 62 milesThe 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.

Where does space end?

No, they don’t believe there’s an end to space. However, we can only see a certain volume of all that’s out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn’t had time to reach us yet, so we have no way of knowing such a galaxy exists.

Does space ever stop?

In theory space goes on and on… It’s because of the shape of space. Our part of space, or the observable universe, has a special shape: it is flat. That means if you and a friend each had your own rocket ship and you both took off and travelled in a straight line, forever and forever, you would never meet.

Where does the atmosphere end and space begin?

Very roughly, it starts about 100 kilometers above the Earth, but there is still part of the Earth’s atmosphere even at this altitude.

Where does space begin and why?

Broadly, most experts say that space starts at the point where orbital dynamic forces become more important than aerodynamic forces, or where the atmosphere alone is not enough to support a flying vessel at suborbital speeds.
