How far from the shore can you see until the horizon?
According to Maryln Van DeSavant I seem to recall she said 7 miles. From basic geometry, you get that the distance to the horizon is D=sqrt(2Rh) where D = distance to horizon R = radius of earth h = height of observer, which would be the height of your eyes. R and h have to be in consistent units, of course. In feet the radius of the earth is about 4000 mi * 5000 ft/mi or 20 million feet. Standing on the shore, your eyes are maybe 5 feet above the surface, so D=sqrt(2*20e6*5)= 14000 feet, or a little under three miles. There are some other effects that make that number a little different. Refraction bends your line of sight, so you can see a little bit farther. If you're looking at an object on the water, like a ship, you also get the distance on the other side of the horizion that corresponds to the height of the target. ==How to calculate the distance yourself== To get an "approximate" distance to the oceanic horizon from a particular observation point, take the square root of the height of the observation point, add 22.5%, and that will give you the distance in statute miles. For example, if your eyes were 6 feet off the ground, and you stood atop a 50' tower, your observation point would be 56'. The square root of 56' is 7.48. Add 22.5% of 7.48 (1.68) to 7.48 and you have 9.16 statute miles from your eyes to the horizon.
How far you can see ahead becomes shorter as you reach a hill top?
Yes. The hilltop is your horizon line. As you approach the top of the hill, the distance between you and your horizon becomes inches, and you cannot see down the other side until you reach the top. Read More

How far can the human eye see to the horizon?
Visible distance (in nm) = 1.17 x the square root of the height (in feet) This means, sitting in my sea kayak, the "horizon" is really only about 2 miles away. However, a 50 foot tree on the shore line could be seen 8.5 miles away. ! Read More

Is it impossible to see objects as far as the distance of the moon and the sun?
No, it is not impossible. After all, you see the Moon and the Sun.The farthest object you can see with the naked eye is the Andromeda Galaxy, at a distance of about 2.5 million light-years. With powerful telescopes, we can see galaxies that are several billions of light-years away. Read More

How far can you see to the horizon on land?
I asume that you mean, standing on land looking out over the ocean. The distance to the horizon would depend on the height of your eye above sea level. If the height of your eye is 6 feet the horizon is about 3.3 statute miles . Read More
Is it be impossible to see any object the distance of the moon or the moon?
Our eyes can only see as far as the horizon, due to the curvature of the Earth. For instance, an observer standing on a hill 100 feet (30 m) in height, their horizon is at a distance of 12.2 miles (19.6 km). Obviously, without the restriction of a horizon, we can look out far into space on a dark night and see our moon and many stars and planets with the naked eye - even… Read More

Because that's all you can see of the horizon. Tall people see a further horizon, shorter people see a closer one. Read More

How far away are clouds on the horizon?
Depends on the geography of the area. In a very flat place on land you can see about five miles to the horizon. Somewhere very cold like in Antarctica on the ice sheets the cold can actually bend light allowing you to see Hundreds of miles. On water you can see about 25 miles. Read More
If Human eyes have 10 miles of visibility how do we see the sun and moon?
Human eyes don't have "10 miles of visibility"; it simply doesn't work that way. The limitation of our eyes is related to how much light must enter the eyes. You can see an object that is in line of sight, and sufficiently bright so that we get enough light from the object into our eyes. That means that brighter objects can be farther away, and still be seen. You can see SOME stars (stars that… Read More

How far can you see to the horizon on water?
A very rough or "ball park" figure is about 20 miles. Comment: It depends on your height above the water. You could only see 20 miles if you were well above sea level. If you are standing more or less at sea level, with your eyes just a few feet above the water level, you could see only about 3 or 4 miles. For example: Eye level at 6 feet: horizon at about 3 miles… Read More
