Answering your question, from the altitude of 3,000 mi (4,800 km) one can see $21.4842\% \approx 21.5\%$ of the Earth's surface. I have typed it in the Google calculator here, so you can use it, just substitute the Earth radius of 6371 km and the altitude 4800 km for the numbers you would like.

A person walking around on the surface of the earth has his eyes elevated about 0.002 km (6 feet) away from the surface. Using this equation, if the earth were perfectly spherical, then a person standing on earth's surface can see about 0.000016% of the earth's surface, or about 82 square kilometers (32 square miles).

India: 75% Off World: 40% Off. This course explores the concept of how much of the Earth can be seen at once. The learning outcomes include understanding the distance to the horizon, Earth's curvature, surface roughness, and texture. The course covers topics such as the Earth's surface features, state flatness, and the Roche limit.

The horizon of the Earth is a little over 20 feet away from where you are standing. If you are standing on top of Denver, then about 15 feet to one side you can see San Francisco, and about 15 feet to the other side you can see Chicago. At this same scale, the Earth that you are standing on would be a sphere with a diameter of about 160 feet.

The fraction of (one-half of) the surface of earth one can see at an altitude h is simply given by: F = h / (h + R) where R is the radius of the earth. So, if you go about one earth radius high (which is about 6370 kilometers or 3960 miles) you can see 1/2 of the most you can see. Once you go as far as the moon (roughly 400 000 kilometers away

You would have to be infinitely far away from a sphere in order to see exactly 50% of its surface all at the same moment. Using simple geometry, you can prove that an observer that is a distance d away from the surface of a sphere with radius R can only see a percent area A of the sphere's surface as given by the equation: . A = 50%/(1+R/d) . The Earth has a radius of about R = 6371 km and the

From just 3 m above the surface, you can see the horizon 6.2 km apart. If you are 30 m high, then you can see up to 20 km far away. This is one of the reasons why the ancient cultures, at least since the sixth century BC, knew that the Earth was curved, not flat. They just needed good eyes. You can read first-hand Pliny (1st century) on the

I'm going to assume that you want to see half of the Earth, as half of the Earth cannot be seen. First of all, seeing 50% of the Earth isn't really possible, no matter how far away you get. So, I'm going to set as a goal that one can see 45% of the circumference of the Earth, as I doubt anyone would be able to tell the difference once one has

https://www.reddit.com/r/vsauce/comments/6ntugk/how_much_earth_can_you_see_at_once/
Good point, but slight correction: Two eyes only allow you to see >=50% of the horizontal dimension, not the vertical one. Sure, you can compensate for that by seeing more than 50% in the horizontal dimension to get to >= 50% of the surface area, but your calculations would have to be adjusted. 3. Reply.

Influenced by the work of Thomas Malthus, 'carrying capacity' can be defined as the maximum population size an environment can sustain indefinitely. Debate about the actual human carrying capacity of Earth dates back hundreds of years. The range of estimates is enormous, fluctuating from 500 million people to more than one trillion.

https://physics.stackexchange.com/questions/25659/how-much-sky-do-we-see-at-any-one-moment
Different animals have different fields of view, depending on the placement of the eyes. Humans have an almost 180-degree forward-facing horizontal field of view, while some birds have a complete or nearly-complete 360-degree field of view. In addition, the vertical range of the field of view in humans is typically around 100 degrees.

It starts at 50% and goes to 100% as we get to distances a few earth radii out. But you were interested in very short distances: Here we can see the effect of small height changes. In particular, for your 6 foot scenario, you can see $$ S(6 \text{ feet}) = 50.04 \% $$ of the sky from purely geometric considerations.

It is 37 km to the horizon. Clear day. Beautiful color. In one sense, you can see a whole lot of nothing -- no cars, buildings, people -- for kilometers. But if you zoom in on this image, you will see details on the horizon that will give you a real feel for what you can resolve. Below is a low-res thumbnail. The high-res image is here.

Since you can see all the way to the E and W horizons at any time, you can subtract 6H RA to the value at sunset twilight and add 6H to the RA to the value at dawn twilight (roughly). So now you have some number of hours of RA that are visible over the course of the night. Normalize that to 24H if necessary (i.e., you can't have more than 100%!).
