How long does it take to travel around the earth now 5

And the faster way? , but not across the Pacific Ocean. You're also flying.

It takes less than a year to go around the globe. If we really want to calculate the specific time for man to circle the earth, we must first discard all uncertain factors. For example, environmental factors, geographical factors, etc., only calculate the simple walking speed time of people, and so on.

How long would it take for a person to circle the earth around the equator and use it as the benchmark?

According to all the above calculations, the length of the earth's equator is about 40,000 kilometers, and a normal walking speed is about 5km h, which of course cannot be compared with the fastest flying animals in the world, and the final calculation result is that if a person does not eat or drink, it takes about 8015 hours to circle the earth, and it takes 334 days to calculate, which is less than a year.

However, some people feel that this calculation method is inaccurate, because the human body is not a machine and can walk at high speed all the time, which means that it is impossible for people to walk for more than 300 days in a row, especially without rest.

But now it's just speculation, and many times you don't know what the truth looks like until you actually do it. Of course, some people say that you can use a machine to imitate the speed of a person's movement, and then you can know how long it takes for a person to circle the earth by calculating. It may not be possible that in the future, someone will try it themselves in order to get the answer.

The Earth is an ellipsoid with flattened poles and a slightly bulging equator. The average radius is about 6,371 km.

Then the circumference of the earth is: 2 r=2 kilometers.

After long-term precise measurements, scientists have found that the earth is not a regular sphere, but an irregular elliptical sphere with slightly flattened equators at the poles, exaggeratedly speaking, a bit like a "pear", called a "pear-shaped body". The Earth's equatorial radius is about long, which is so small compared to the average radius of the Earth that it can still be regarded as a regular sphere when viewed from the perspective of space. If a globe with a radius of 1 meter is made according to this scale, the equatorial radius is only about 3 mm longer than the polar radius, which is difficult to detect with the human eye, so it is always made into a regular sphere when making a globe.

The international standard of rice is set like this:

1 m = 1 40000000 length of the equator.

So, the equator is 40,000 kilometers long, unless this criterion changes.

If it's in the sky, it must be more than 40,000 kilometers, depending on how high it is.

Can a circle at the pole be called circumnavigating the earth? It's like if you stand on the playground and go around and say you spared the playground for a week.

If the earth circles the sun, it is.

2*100,000,000,000

If it's an autobiography at some point on the surface of the earth.

On the equator it is 40,076 km. Other latitudes are the values on the equator multiplied by the cosine of latitudes.

The circumference of the Earth is: 2 r=2 km.

The Earth is an ellipsoid with flattened poles and a slightly bulging equator. The average radius is about 6,371 km.

After long-term precise measurements, scientists have found that the earth is not a regular sphere, but an irregular elliptical sphere with slightly flattened equators at the poles, exaggeratedly speaking, a bit like a "pear", called a "pear-shaped body". The Earth's equatorial radius is about long.

If you go around the earth along the equator, it is 40,000 kilometers.

One circumference around the Earth is kilometers.

The equator is the longest circumferential line in the trajectory of points on the Earth's surface that rotate with the Earth. Equatorial radius 6, equatorial circumference.

It divides the earth into two hemispheres, north of it and south of it is the southern hemisphere, which is the baseline that divides latitude. The equator has a latitude of 0°, which is the longest latitude on Earth.

The equator is the place where gravitational acceleration is minimal on Earth.

About 40,000 kilometers (along the equator.

But the Earth is an ellipse, and the data measured for each different path is different: around the meridians.

One lap is about 39,900 km

The equator is the longest circumference of the trajectory of points on the Earth's surface with the rotation of the Earth, 40,00 kilometers long.

One rotation of the earth is more than 400,000 kilometers.

40,000 kilometers, the diameter of the earth is 12,800 kilometers.

The main thing is to see whether it is calculated according to the flat ground or the terrain is included together.

Equatorial circumference.

Meridian circumference.

Sit on the ground and travel 80,000 miles a day, 80,000 miles.

If it is the equator, it is about more than 40,000 kilometers.

It depends on which line of latitude you are winding from. If at both poles, it is small.

The circumference of the equator is 40, km

The circumference of the meridian circle is 40, km

The average circumference is 40, km

I haven't walked it, it seems to be a long, long time.

How many kilometers does a globe go around? I know, I won't tell you.

How many kilometers does the earth go around? About 400,000 km. If you are away from candy, you are wrong! Russia is 40 thousand km!

About 40,000 kilometers (along the equator), because the earth is ellipsoidal, the measured data around different paths are different: about 39,900 kilometers around the meridian

The radius of the equator is slightly longer, the radius of the poles is slightly shorter, and the polar axis is equivalent to the axis of rotation of an oblate sphere. According to the International Union of Geodesy and Geophysics in 1980, the main data on the shape and size of the Earth are as follows:

Equatorial radius. Radius of the poles.

Average radius. Flattening rate 1

Equatorial circumference. Meridian circumference.

Surface area volume 10832 108km3In fact, the true shape of the Earth is slightly different from that of the above-mentioned oblate sphere. Its southern hemisphere is slightly thicker and shorter, and the antarctic is concave inward about 30m; The Northern Hemisphere is slightly slender and long, with the North Pole protruding about 10 m upward. So it is an exaggeration to say that the true shape of the earth is slightly pear-shaped.

The Earth is a sphere.

Watch you go around in a circle.

40,000 km around the equator

It is only 1 meter around the pole.

The circumference of the Earth's equator is about 40,000 kilometers, and the ancient Greek Eratosthenius calculated that the circumference of the Earth is 39,250 kilometers.

About 40,000 kilometers (along the equator), because the earth is ellipsoidal, the measured data around different paths are different: about 39,900 kilometers around the meridian

The circumference of the Earth is 39,942 kilometers at the poles and about 40,000 kilometers at the equator.

If you count the equator, it's 80,000 miles. If it's somewhere else, it's closer.

One rotation of the Earth is 23 hours, 56 minutes and seconds, or an approximate 24 hours. The Earth rotates from west to east on its axis of rotation, rotating counterclockwise from the North Pole and clockwise from the South Pole. The Earth's axis of rotation is angled to the ecliptic plane, perpendicular to the equatorial plane.
