Space officially begins astir 100 km supra the Earth’s surface, a bound known arsenic the Kármán line. But Earth isn’t a cleanable sphere — it’s somewhat flattened astatine the poles and bulged astatine the equator. Because of this shape, the region from the centre of the Earth to the aboveground isn’t the aforesaid everywhere. So, being closest to abstraction doesn’t conscionable beryllium connected a mountain’s tallness — it besides depends connected wherever it’s located connected the planet.
If we went by the elemental logic that the tallest upland indispensable beryllium closest to the sky, the reply would beryllium Mount Everest. But surprisingly, it’s not!
Because of Earth’s shape, points adjacent the equator are really farther from the halfway of the Earth, making them person to outer space. That’s wherefore a upland adjacent the equator tin beryllium person to abstraction than adjacent the tallest highest successful the world!
The closest spot revealed
So, which state is closest to space?
It’s Ecuador, location to Mount Chimborazo, a dormant volcano adjacent the equator.
Even though Mount Everest is taller supra oversea level, the highest of Chimborazo is really farther from the halfway of the Earth. Because Earth bulges astatine the equator, this makes Chimborazo the closest constituent connected Earth to outer space.
Fun facts
Astronauts astatine the International Space Station orbit Earth astir 400 km supra — that’s conscionable 4 times higher than wherever abstraction officially begins
Planes alert astatine astir 10–12 km — acold beneath the Kármán line.
Did you know?
If you stood connected Mount Chimborazo successful Ecuador, you’d beryllium 2,000 metres person to abstraction than if you were lasting connected Mount Everest!
