What is the space above Earth?

Outer space does not begin at a definite altitude above the Earth’s surface. 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.

What is above and below Earth in space?

“Above” and “below” don’t have meaning outside of a gravity well. Every direction that leads into the sky, and eventually space, from the surface of the Earth is “up.” “Down,” likewise, is toward the center of the planet, from any point on the surface: north, south, equatorial, or anywhere in between.

Why is it called the Kármán line?

The Karman Line, by definition, is an attempt to define a boundary between our atmosphere and outer space. Its name derives from Hungarian-American engineer and physicist Theodore von Karman, who, in 1957, attempted to determine an altitude limit.

What is the black in space?

Because space is a near-perfect vacuum — meaning it has exceedingly few particles — there’s virtually nothing in the space between stars and planets to scatter light to our eyes. And with no light reaching the eyes, they see black.

What is the darkest planet in the universe?

(The darkest planet discovered so far is the pitch-black exoplanet TrES 2B, or Kepler-1b, located about 750 light-years away, which absorbs more than 99 percent of the light that hits it.)

How far is each planet from the Sun?

How far is each planet from Earth? (Intermediate) Planet Average distance from Sun in AU Mercury 0.39 Venus 0.72 Earth 1.00 Mars 1.52

What is the average temperature of outer space near Earth?

The average temperature of outer space near Earth is 283.32 kelvins (10.17 degrees Celsius or 50.3 degrees Fahrenheit).

What is the difference between the atmosphere and outer space?

The layers of the atmosphere are drawn to scale, whereas objects within them, such as the International Space Station, are not. Outer space is the expanse that exists beyond Earth and between celestial bodies.
