How far is the horizon over water? Best Answer: It depends on your height above the surface of the water. where h is the height above ground or sea level (in meters) of the eye of the observer. For an observer standing at sea level with h = 1.70 metres (5 ft 7 in) (average eye-level height), the horizon is at a distance of 4.7 kilometres (2.9 mi).

How far away is the horizon? In that case, your horizon is 5.1 km (3 miles) away. That also sounds about right to me. But now let’s say you are in your hotel overlooking the beach, and on your floor your eyes are 20 meters off the ground. The horizon is then 16 km away, much farther than before.he key thing here is that at the visible horizon, the angle between your line-of-sight and the radius line of the Earth is a right angle (marked in the diagram). That means we have a right triangle, and — reach back into the dim, dusty memory of high school — that means we can use the Pythagorean Theorem to get d.

How many miles above us is the edge of the atmosphere? An altitude of 120 km (75 miles) marks the boundary where atmospheric effects become noticeable during re-entry. The Karman line, at 100 km (62 miles), is also frequently used as the boundary between atmosphere and outer space. For all intents and purposes, space starts at about 62 miles. And no, it has absolutely zero to due with the Earth's gravity.

How far is the horizon over water? For observers standing on a hill or tower 100 feet (30 m) in height, the horizon is at a distance of 12.25 miles (19.71 km). If the US Navy ever said the horizon was 14 miles away, it must have been from the masthead of a large ship - about 130 feet (39.82 meters) above the water. Of the 244 feet between keel and masthead of a Nimitz-class carrier, about 38 is below the waterline, and about 150 feet is the island superstructure.

How far away is the horizon? Sanity check: if you are 0 meters off the surface of the Earth (lying down really really flat), the horizon is 0 kilometers away. That makes sense -- you're tangent to the surface! So the first line sounds right. Now imagine you are standing on a beach, looking out over the ocean to the horizon.

When I stand at the water's edge and look out over the ocean, how far away is the horizon? Because of the curvature of our planet, the distance between you and the horizon when you look out over the ocean depends on your height above the surface of the water. The following diagram shows you how the distance to the horizon can change depending on the height of the observer:

- When in a tall building, the horizon can be as far as about 40 miles. From the ISS, the distance to the horizon is over 1000 miles. So from horizon to horizon, the section of the Earth you can see at any one time is a patch about 2000 miles across, almost enough to see the entire United States at once.

What is the distance to the horizon? When standing at sea level, the distance to the horizon in miles is approximately the square root of one-and-a-half the person's height in feet. For example, if a person was … six feet tall, the horizon would be about three miles away. miles. Answer: The distance to the horizon on the ocean is a function of the height of the observation point. In general (and with thanks to Pythagoras) it is: d=(h(D+h)) … 0.5 where d = distance to the horizonD = diameter of the Earthh = height of the observer above sea level.

How Far Away Is The Horizon? Now that we’re thinking about horizons, here’s another cool thing to think about. The horizon is three miles away on earth. But elsewhere in the solar system it’s closer or farther, depending on the size of the body you’re standing on! Take the moon. The moon is two thousand, one hundred and sixty miles in diameter, only about one quarter the size of the earth. So the curvature at its surface is much more noticeable, and the horizon is much closer. It’s only about 1.5 miles away.

How far away can you see mountains from? Best Answer: The horizon distance as seen from an elevated position can be calculated by: Dist to horizon = Sq root of, ((radius of earth + hight above ground)^2 - radius of earth^2) http://www.boatsafe.com/tools/horizon.ht... says if you are on Mt Everest, 29006 feet high, unobstructed horizon is at 229 miles. So your figure of 800 miles is a bit high, by about 4 to 10 times. But if this girl's city is quite high also, and the planet this is on is much larger than the Earth (curve of horizon is larger) then 800 miles might be possible.

- No, as long as the Moon is above the horizon, you are a little closer to the Moon than stated in the Moon Distance Calculator. This is because the calculator shows the distance between the center of the Earth to the center of the Moon. So, when you see the Moon in the sky, the Earth's curvature takes you a little closer to the Moon than the distance stated in the calculator.

Distance to The Horizon Distance to horizon. In order to determine how far away the horizon is for any given observer, first determine how far above sea level the observer's eyes are. If the observer is standing on the surface of the ocean, his eyes might typically be somewhere between 140 and 200 centimeters above sea level. Look this number up in the first column in the below table. The second column then tells you how far away the horizon is.

Distance to The Horizon Its highest point is some sails that are 16 meters above the surface of the sea. Ut'kikk's horizon distance (based on a 12 meters height) is 13 km. The target's horizon distance (based on a 16 meters height) is 14.5km (extrapolating a bit since the table doesn't actually list 16m). 13 km plus 14.5 km is 27.5 km. Since this is much less than the distance between the two ships (43 km), Ut'kikk cannot see the other ship yet.

TEACHERâS GUIDE For AEROSPACE: THE JOURNEY OF FLIGHT HOW FAR UP DOES THE EARTH'S ATMOSPHERE EXTEND? Atmosphere is the gaseous envelope of air that surrounds the earth. The air extends as far as 1,000 miles above the surface of the earth. Scientists divide the earth's air into four layers: the troposphere, the stratosphere, the mesophere and the thermosphere. Nitrogen makes up 78 percent of the world's atmosphere and oxygen makes up 21 percent.

How Far Can You See in the Universe? If you get to an altitude of 20 meters, the horizon stretches out to about 11 km. But we can see objects in space which are even more distant with the naked eye. The Moon is 385,000 km away and the Sun is a whopping 150 million km. Visible all the way down here on Earth, the most distant object in the solar system we can see, without a telescope, is Saturn at 1.5 billion km away. In the very darkest conditions, the human eye can see stars at magnitude 6.5 or greater. Which works about to about 9,000 individual stars. Sirius, the brightest star in the sky, is 8.6 light years. The most distant bright star, Deneb, is about 1500 light years away from Earth.

- At many locations, the true horizon is obscured by trees, buildings, mountains, etc., and the resulting intersection of earth and sky is called the visible horizon. When looking at a sea from a shore, the part of the sea closest to the horizon is called the offing.The word horizon derives from the Greek ὁρίζων κύκλος horizōn kyklos, separating circle, from the verb ὁρίζω horizō, to divide, to separate, and that from ὅρος (oros), boundary, landmark.ith d in miles and h in feet, Examples, assuming no refraction: 1  For an observer on the ground with eye level at h = 5 ft 7 in (1.70 m), the horizon is at a distance of 2.9 miles (4.7 km). 2  For an observer standing on a hill or tower 100 feet (30 m) in height, the horizon is at a distance of 12.2 miles (19.6 km).
