How many miles can you see before the earth curves?

The old saying turns out to be just about true. Forasix-foot tall person, the horizon is a little more than3miles (5 km) away. Geometry tells us that the distance ofthehorizon – i.e. the farthest point the eye can seebeforeEarth curves out beneath our view – depends simply ontheheight of the observer.

Herein, can you see the Earth's curvature?

It is possible to see the effect ofthecurvature of the earth from sea level(shipsdisappearing over the horizon). To actually seethecurvature directly (ie to be able to see thehorizonas an arc, rather than a straight line) requires an altitudeofover 50,000 feet.

Also Know, how many miles can you see out to sea? Boat captains say, on average, you can seeshipson the horizon or land at about 12 miles. A roughformula athttp://science.howstuffworks.com Examples: For anobserver standingon the ground with h = 1.70 metres (5 ft 7 in)(average eye-levelheight), the horizon is at a distance of 4.7kilometres (2.9mi).

Similarly, you may ask, how much does the earth curve in 6 miles?

However, it turns out that while the earthdoescurve 8 inches in one mile, it does not take9miles to curve 72 inches. To show this, let usreturnto the Pythagorean Theorem method used by Harley, butusing6 feet for the curvature.

How much does the earth curve in 1 mile?

The Earth has a radius of approximately3965miles. Using the Pythagorean theorem, that calculates toanaverage curvature of 7.98 inches per mileorapproximately 8 inches per mile (squared).

At what height is Earth's curvature visible?

It's hard to see the curvature of theearthfrom an altitude of 7 miles or 37,000 ft(typical cruisingaltitude of a jetliner) but easy to seefrom 250 miles(typical altitude of the ISS). The line ofsight from anaircraft at 37,000 feet = 235 miles. That's onlyabout 3.4 degreesof the earth's surface.

How high is space?

In the US, "space" begins at 80.4km (50 miles),or264,000 feet. General international consensus sets a similarlimitfor the start of space as 100km (62 miles), or 380,000feet."Low Earth Orbit" (LEO), where many satellites live, goesfrom 160km(100 miles, 525,000 feet) to 2,000km (1,240 miles, 6.5millionfeet).

How far can you see at 30000 feet?

So, at 10,000 feet you can see 122 miles,at30,000 feet you can see 211 miles, and at 40,000 feetyoucan see 244 miles. Of course, if you look "above"thehorizon, you can see the sun at 93,000,000 miles andatnight, even further, to the stars.

Can you see curvature from Everest?

But the curvature they show is not that oftheEarth. Earth's curvature can't be visually seen fromanylocation on the ground, even from Mount Everest.Studiesshow that the threshold altitude for seeingthecurvature is about 35,000 ft (10,668 m).

Can stars be seen in space?

Fast exposure times means they can getgoodpictures of the bright Earth or lunar surface, but it alsomeans nostars in the picture. Even in space,stars arerelatively dim, and simply don't produce enoughlight to show up inphotos set for bright sunlight.

How do you measure curvature?

To measure the curvature at a pointyouhave to find the circle of best fit at that point. This iscalledthe osculating (kissing) circle. The curvature of thecurveat that point is defined to be the reciprocal of the radius oftheosculating circle.

How do you calculate the radius of the earth?

Compute the radius of theearthusing the formula C (circumference) = 2 x pi xr(radius). Erastosthenes' formula would looklikethis: 39,350 = 2 x 3.14 x r, or 6,267 kilometers.

How far can you see from a plane?

What if you're a lot higher up, like inanairplane? At a cruising altitude of 39,000 feet (12,000meters;typical for a cross-country flight) the horizon is 391 km(235miles) away! That's a surprisingly long way; in general thatmeansyou could be looking across one or more statesin theUS.

How are nautical miles different?

A nautical mile measures distance and aknotmeasures speed.
A nautical mile is based on the circumferenceofthe earth, and is equal to one minute of latitude. It isslightlymore than a statute (land measured) mile (1nauticalmile = 1.1508 statute miles ). Nauticalmiles areused for charting and navigating.

Horizon, in astronomy, boundary wherethesky seems to meet the ground or sea. (In astronomy itisdefined as the intersection on the celestial sphere of aplaneperpendicular to a plumb line.) The higher the observer, thelowerand more distant is his visible horizon.
