#### Question: How Far Is The Curve Of The Earth?

The horizon’s arc is curved. If you look at the Earth’s surface from an altitude of roughly 2,640 kilometres (1,640 mi), a circle with an angular radius of 57.3° emerges. This corresponds to an altitude of around 2,640 km (1,640 mi).

## How far can you see before the curve of the earth?

The spherical shape of the Earth The Earth bends at a rate of around 8 inches every mile. Therefore, standing on a flat surface with your eyes 5 feet or so above the ground, the farthest edge that you can see is approximately 3 miles distant while looking straight ahead.

## How far can the human eye see on the ocean?

It would be 4.7 kilometers away if measured at sea level. We can almost certainly improve our maximum line of sight if we incorporate another variable in addition to the curvature of the globe (which is practically constant), and if we raise the height of the observer.

## At what height can you see the curve?

According to visual daytime observations, the lowest altitude at which the curvature of the horizon can be noticed is at or slightly below 35,000 feet if the field of vision is wide (60 degrees) and the sky is almost clear.

## How far can you see at 35000 feet?

How far can you see while you’re flying at 35,000 feet? – Quora is a question and answer website. The distance between the Earth and the Andromeda galaxy is 2.5 million light years if you stare towards the galaxy on a clear, dark night and see its hazy glow. For example, if you are flying in an airplane at 35,000 feet, that is 10,668 meters (35, 000 feet divided by 3.28 feet per meter = 10,668 meters).

## How many miles can you see on a clear day?

(Photo courtesy of the National Oceanic and Atmospheric Administration.) It’s possible to see for miles and miles and miles in the distance on a clear day. It turns out that the ancient adage is almost entirely correct. The horizon is a little more than 3 miles (5 kilometers) away for a person who is six feet (182.88 cm) tall, according to the International Standard Time (IST).

## How Far Can dogs see?

The typical seeing distance of a dog is 40 meters on average, according to experts. However, the picture will look fuzzy, and it will be necessary to validate it with all three canines’ sensory capabilities. A dog can see the thing clearly from 20 feet (6 meters) away, which is around 6 meters.

## Can you see 50 miles away?

The farthest point that you can view is around three miles away. 6 miles: The typical 747 passenger airliner travels at an altitude of approximately 6.6 miles above the ground. On clear days, city structures may be visible from as far away as 50 miles away (assuming you’re standing on level terrain).

## How high do you have to be to be in space?

The Kármán line, which marks the beginning of outer space at a height of 100 kilometers (62 miles) above sea level, is traditionally used in space treaties and for the preservation of aerospace records. The Outer Space Treaty, which went into force on October 10, 1967, created the legal basis for international space law and set the framework for international space law.

## Where on the surface of the earth is the radius maximum?

Any radius lies between the polar minimum of approximately 6,357 km and the equatorial maximum of approximately 6,378 km, regardless of the model used (3,950 to 3,963 mi).

## How far away are clouds on the horizon?

If you’re standing on level ground in clear weather with plenty of light, you can see clouds on the horizon from around 66 kilometers distant if you’re looking straight ahead.

## Why do commercial airplanes fly at 35000 feet?

Approximately 35,000 feet is the altitude at which a satisfactory balance between operational expenses and fuel efficiency can be reached, which is why commercial airplanes often fly at that level. It is also becoming increasingly difficult for oxygen to reach the cells, making it impossible for fuel engine systems to function properly.

## How far can the human eye see another person?

According to a recent study, the human eyesight limit is only 1.6 miles.

## How far away can a pilot see?

Despite travelling at 39,000 feet (12,000 meters), which is usual for a cross-country journey, the horizon is 391 kilometers (235 miles) distant! That’s a pretty big distance, and in most cases it means you’ll be looking over one or more states in the United States.
