How far in space do you have to be to see the whole Earth?
If 90\% is good enough for you, you only need to go 57000 kilometers (35600 miles) high from the surface of the earth. If you want 100\%, that you just are not going to get at any finite distance.
Can you see Earth in space?
From the window of the ISS, the surface of the Earth looms large. In the daytime, you can clearly see major landforms. At night, from Earth orbit, you see the lights of Earth’s cities. As we pass the moon – some quarter million miles (about 380,000 km) away – Earth looks like a bright ball in space.
How far is space from Earth in feet?
International law does not define the edge of space, or the limit of national airspace. The FAI defines the Kármán line as space beginning 100 kilometres (54 nautical miles; 62 miles; 330,000 feet) above Earth’s mean sea level.
What 3 things can you see from space?
From the world’s biggest rivers and mountains to ancient pyramids, we look at the most incredible sights on earth that can be seen from space.
- The Great Pyramids of Giza, Egypt.
- The Grand Canyon, USA.
- The Himalayas.
- Great Barrier Reef, Australia.
- Amazon River.
- Palm Island, Dubai.
- Ganges River Delta.
How far away in space could you view Earth with the eye?
How far away in space could you view Earth with the eye alone? Considering only brightness, the answer is about 9 billion miles (14 billion km) away, about the distance of Neptune or Pluto.
What is the distance from the sun to the Earth’s orbit?
One AU is the distance from the Sun to Earth’s orbit, which is about 93 million miles (150 million kilometers). When measured in astronomical units, the 886,000,000-mile (1,400,000,000-kilometer) distance from the Sun to Saturn’s orbit, is a much more manageable 9.5 AU.
How close to the Earth can you see 50\% of it?
One must travel an infinite distance before 50\% of the planet is visible. Any closer and the distance between your eyes will mean that less than 50\% is visible – as your eyes are not the diameter of the earth apart, at any real distance it is only possible to approach the 50\% boundary.
How do you find the distance to the Earth in miles?
The human visual field of view is approximately 120 degrees in both the horizontal and vertical directions. If we construct a right triangle where one angle is 60 degrees (half of 120 degrees), “d” is the distance to the earth, and “r” is the radius of the earth, then d = r/tan (60) = 6371 km/1.732 = 3678 km = 2285 miles.
