#### How Far Earth Curve At Sea Level?

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 sea level before the earth curves?

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.

## How far away is the horizon at sea level?

Another factor to consider is that the more away the observer’s eyes are from sea level, the further away they are from the horizon. For example, under typical air circumstances, the horizon is about 5 kilometres away for an observer who is 1.70 metres (5 ft 7 in) above sea level with his or her eyes level above sea level by 1.70 metres (5 ft 7 in) (3.1 mi).

## How far can a 6 foot man see at sea level?

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). Geometry teaches us that the distance between the horizon and the observer’s eye – that is, the farthest point the eye can see before the Earth bends out under our perspective – is solely determined by the observer’s height.

## What is the maximum distance you can see at sea level?

The curvature of the planet restricts the range of vision to 2.9 miles at sea level due to the curvature of the world. The square root of an individual’s altitude multiplied by 1.225 is the formula for finding how many miles he or she can see from a certain height.

## How far can the human eye see if the earth was flat?

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.

## 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 far away is the horizon at 6 feet?

The horizon is approximately 3 miles away from a height of around 6 feet.

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

Due to the Earth’s surface curving out of sight, a 6ft man standing and staring out to the horizon can see around 5 kilometers (miles) distant. Our capacity to see, on the other hand, stretches well beyond the horizon. Also affecting normal vision is the quantity of dust and pollution in the air, which typically reduces normal vision to fewer than 12 miles in most cases.

## How far over the horizon can you see?

Because the Earth’s surface bends out of sight, a 6ft man standing and staring out to the horizon can see around 5km afar. Although we have the ability to look to the horizon, our vision extends far more than that. It also relies on the quantity of dust and pollution in the air, which typically reduces normal eyesight to less than 12 miles in most cases, among other factors.

## What is the longest distance on earth?

What are the two most remote locations on the planet?

- From Rosario, Argentina to Xinghua, China, the distance is 19,996 kilometers (12,425 miles)
- from Lu’an, China to Ro Cuarto, Argentina, it is 19,994 kilometers (12,424 miles)
- from Cuenca, Ecuador, to Subang Jaya, Malaysia, it is 19,989 kilometers (12,421 miles)
- and from Shanghai, China, to Concordia, Argentina, it is 19,984 kilometers (12,417 kilometers)

## At what altitude can you see the entire earth?

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 underwater?

Turbidity, which reduces the range of underwater vision, is a common occurrence. In exceptionally pure water, visibility can reach as far as 80 meters, and a record Secchi depth of 79 meters has been recorded in the Eastern Weddell Sea, Antarctica, from a coastal polynya on the continent.
