Hello, dear readers of the site "I and the World"! We are glad to welcome you again! Which do you think is the most Big city in the world and what is it called? In our new article, we want to talk about cities and present the top 10 largest in the world in terms of area and population.
10th place - New York - 1214.4 sq. km
America starts the list. If you look at the population for 2017, then the city is small - 8,405,837 people. Quite young, about 400 years old.
In what is now New York there were Indian tribes. Arrows, dishes and other Indian attributes are found here. Throughout the 19th century, emigrants from different countries, due to which it grew. It includes several islands, the largest of them is Manhattan. People of almost all religions live in it, but Christians predominate.
We give 9th place to Mexico City - 1485 sq. km
The population of the capital of Mexico is 9,100,000 people. Mexico City was founded by the Aztecs in 1325. According to legend, the God of the Sun commanded them to come to this place.
At the beginning of the 16th century, Mexico City was the most beautiful in the Western Hemisphere, until it was destroyed during the reign of Cortes, but soon rebuilt again. It is located at an altitude of more than 2000 km above sea level and is surrounded by mountains.
London is in 8th place - 1572 sq. km
London is the capital of Great Britain and The largest city in the country. It was founded in 43 AD. e. There are currently 8,600,000 people living in London.
The terrible plague of the 17th century claimed about 70,000 lives. This is a place of remarkable historical and architectural monuments: the Tower, Buckingham Palace, St. Paul's Cathedral and others.
We put Tokyo in 7th place - 2188.6 sq. km
But the population is quite large - 13,742,906 people. Tokyo is one of the modern cities and the capital of Japan. Even after living here for a month, you will not see all the sights.
The main part is solid concrete and wires. Tokyo has been inhabited by human tribes since the Stone Age. For several years from 1703 to 2011, Tokyo suffered many earthquakes, and as a result of one of them, 142,000 people died at once.
On the 6th place - Moscow - 2561.5 sq. km
Moscow is the capital Russian Federation, located in the interfluve of the Oka and Volga rivers. 12,500,123 people live here. In terms of length, Moscow is quite long - 112 km. It is an important tourist center of Russia.
The age of the city is still not exactly known, but there are facts that the first settlements appeared on this territory around 8 thousand years BC. e.
Middle of the top - Sydney - 12144 sq. km
The development and history of Australia began from a small settlement. The navigator Cook landed here 200 years ago. Sydney - largest metropolis and the state capital of New South Wales.
4,500,000 people live in the capital. The city is spread in one of the most beautiful bays in the world, where business skyscrapers coexist with cozy beaches, which are always full of tourists.
On the 4th place - Beijing - 16808 sq. km
Beijing is the capital of the People's Republic of China. Huge and bustling, it has a population of 21,500,000 inhabitants.
In the 13th century, it was almost completely burned by Genghis Khan, but rebuilt 43 years later in a different place. Here is the famous architectural monument The Forbidden City is the residence of the rulers.
At the beginning of the 20th century it was occupied by the Japanese. After Russia's victory in World War II and the fall of Japan, the capital became free again.
We give 3rd place to Hangzhou - 16847 sq. km
The city has 8,750,000 inhabitants. The metropolis is famous for its tea plantations and the beauty of nature.
Previously, it was the capital of China, and now a major religious center. In the 19th century, as a result of an uprising, it was partially destroyed and restored in the 50s, where industry began to flourish.
The weaving of folk products, the collection of tea leaves and the production of bamboo products are still manual.
In second place - Chongqing - 82300 square meters. km
Chongqing is the largest city in the world in terms of population - about 32 million people live here. The largest population density is 600 people per sq. km. km.
The metropolis arose 3,000 years ago and at that time was the capital of the kingdom of Ba. Now it is a huge industrial center. There is a large base for the production of cars - 5 factories and 400 - for the production of parts for cars. Real estate construction here is proceeding at such a rapid pace that 10 years of construction for Moscow is 1 year for Chongqing. Old buildings are being demolished very actively, in place of which skyscrapers appear. It is more business than architectural. And the main attraction is the flyovers that entangled the whole city.
We give 1st place to the unusual city of Ordos - 86752 sq. km
Ordos is a ghost town. Where is the strange metropolis, the largest in terms of territory, but empty? In China, they began to build it 20 years ago for people involved in the extraction and sale of coal.
A large city was built with museums, theaters, a stadium. There is everything for the life of a city dweller. But almost no one wanted to move here. Over the past few years, people have increased to 300,000. In a huge settlement, there are so few inhabitants that even in broad daylight, the streets are completely empty.
Beautiful, abandoned houses, museums, cinemas. There are even unfinished buildings - there is no one to build for anyone. Everywhere is clean and tidy. And silence! A metropolis inhabited by "ghosts". There are several in China.
Also, there are cities beyond the Arctic Circle and living there is quite cold. The largest "cold" city is located in Russia - this is Murmansk - 154.4 square meters. km. It is quite small in size and has a population of 298,096 people.
We have shown you a rating of major cities in the world in the photo and with a description. Ten different megacities, with different numbers of inhabitants, with different lengths and architecture. 2018 will be a new year for everyone and everything, and our ranking may change. In the meantime, if you liked the information, share it with your friends.
Tractors are real hard workers. This technique was specially created in order to help a person. sometimes it seems that its possibilities are simply endless. And the dimensions of the tractors are sometimes really impressive. In this review, 10 real giants, which in different areas can be called "the most-most-most" ...
1. Terra Variant-600
Terra Variant (manufactured by HOLMER Maschinhenbau Gmbh) is said by specialists to be the most powerful tractor in Europe, which has sufficient power reserve (Daimler engine from Mersedes-Benz, 490hp or 612hp) and a large haul volume.

It is driven by a powerful 12-cylinder engine (1150hp), which has direct injection, turbocharging and water cooling. For 1 time Komatsu D575A holds 69mᵌ of soil. Its dimensions are: length - 12.7 m, width - more than 7 m, height - 4.87 m.
BONUS
Asso dozer
This giant in the world of bulldozers never saw the world (designed by the Italian company Asso). Motor power - 1300hp, and weight - 183000kg. Bulldozer blade - 7m (in length) and more than 2m (in height). A ripper is located at the back, the height of which is about 3 meters. A powerful hydraulic system is responsible for the control of attachments. The machine was designed in the 80s of the twentieth century (for export to Libya) to develop new territories for construction, however, due to trade embargoes imposed on the country, the finished bulldozer was never sent to the customer. Subsequently, no one has put it into operational use, and until now Asso dozer has remained unclaimed. Most likely, that it will simply be dismantled for scrap metal.
Continuing the theme of unusual technology, we have collected.

Our universe is truly huge. Pulsars, planets, stars, black holes and hundreds of other objects of incomprehensible size that are in the universe.
And today we would like to talk about the 10 biggest things. In this list, we've put together a collection of some of the largest objects in space, including nebulae, pulsars, galaxies, planets, stars, and more.
Without further ado, here is a list of the ten biggest things in the universe.
The largest planet in the Universe is TrES-4. It was discovered in 2006 and is located in the constellation Hercules. A planet called TrES-4 orbits a star that is about 1,400 light-years away from planet Earth.
The planet TrES-4 itself is a ball that consists mainly of hydrogen. Its size is 20 times the size of the Earth. The researchers claim that the diameter of the discovered planet is almost 2 times (more precisely, 1.7) the diameter of Jupiter (this is the largest planet in the solar system). The temperature of TrES-4 is about 1260 degrees Celsius.
To date, the most big star is UY Scutum in the constellation Scutum at a distance of about 9500 light-years from us. This is one of the brightest stars - it is 340 thousand times brighter than our Sun. Its diameter is 2.4 billion km, which is 1700 times larger than our sun, with a weight of only 30 times the mass of the sun. It is a pity that it is constantly losing mass, it is also called the fastest burning star. Perhaps that is why some scientists consider the Cygnus NML to be the largest star, while others consider VY Canis Major.
Black holes are not measured in kilometers, the key indicator is their mass. The most gigantic black hole is in the galaxy NGC 1277, which is not the largest. However, the hole in the galaxy NGC 1277 has 17 billion solar masses, which is 17% of the total mass of the galaxy. For comparison, the black hole in our Milky Way has a mass of 0.1% of the total mass of the galaxy.
7. The largest galaxy
The mega-monster among the galaxies known in our time is IC1101. The distance to the Earth is about 1 billion light years. Its diameter is about 6 million light years and holds about 100 trillion. stars, for comparison, the diameter of the Milky Way is 100 thousand light years. Compared with milky way IC 1101 is over 50 times larger and 2000 times more massive.
lyaxes (drops, clouds) Lyman-alpha are amorphous bodies resembling amoebas or jellyfish in shape, consisting of a huge concentration of hydrogen. These blots are the initial and very short stage of genesis new galaxy. The largest of them, LAB-1, is over 200 million light-years across and lies in the constellation of Aquarius.
In the photo on the left, LAB-1 is fixed by devices, on the right - an assumption of how it may look close.
A radio galaxy is a type of galaxy that emits much more radio emission than other galaxies.
Galaxies, as a rule, are located in clusters (clusters), which have a gravitational connection and expand along with space and time. What is in those places where there is no location of galaxies? Nothing! The area of the Universe in which there is only "nothing" is emptiness. The largest of them is the void of Bootes. It is located in close proximity to the constellation Bootes and has a diameter of about 250 million light years. The distance to the Earth is approximately 1 billion light years
The largest supercluster of galaxies is the Shapley supercluster. Shapley is located in the constellation Centaurus and appears as a bright densification in the distribution of galaxies. This is the largest array of objects bound together by gravity. Its length is 650 million light years.
The largest group of quasars (a quasar is a bright, energetic galaxy) is Huge-LQG, also called U1.27. This structure consists of 73 quasars and has a diameter of 4 billion light years. However, the Great GRB Wall, which has a diameter of 10 billion light years, also claims the championship - the number of quasars is unknown. The presence of such large groups of quasars in the Universe contradicts Einstein's Cosmological principle, so their research is doubly interesting for scientists.
If astronomers argue about other objects in the Universe, then in this case, almost all of them are unanimous in their opinion that the largest object in the Universe is the Cosmic Web. Endless clusters of galaxies surrounded by black matter form "nodes" and with the help of gases - "threads", which outwardly very much resemble a three-dimensional web. Scientists believe that the cosmic web entangles the entire universe and connects all objects in space.
The science
Of course, the oceans are vast, and the mountains are incredibly high. What's more, the 7 billion people that Earth is home to is also incredible. a large number of. But, living in this world, with a diameter of 12,742 kilometers, it is easy to forget that this is, in essence, a trifle for such a thing as space. When we look into the night sky, we realize that we are just a grain of sand in a huge infinite universe. We invite you to learn about the largest objects in space, the size of some of them is difficult for us to imagine.
1) Jupiter
The largest planet in the solar system (142,984 kilometers in diameter)
Jupiter is the most major planet our star system. Ancient astronomers named this planet after Jupiter, the father of the Roman gods. Jupiter is the fifth planet from the Sun. The planet's atmosphere is 84 percent hydrogen and 15 percent helium. Everything else is acetylene, ammonia, ethane, methane, phosphine and water vapor.
The mass of Jupiter is 318 times the mass of the Earth, and the diameter is 11 times greater. The mass of this giant is 70 percent of the mass of all the planets in the solar system. Jupiter's volume is large enough to contain 1,300 Earth-like planets. Jupiter has 63 known moons, but most of them are incredibly small and fuzzy.
2) Sun
The largest object in the solar system (1,391,980 kilometers in diameter)
Our Sun is a yellow dwarf star, it is the most large object star system in which we exist. The Sun contains 99.8 percent of the mass of this entire system, most of the rest of the mass is Jupiter. The Sun is currently 70 percent hydrogen and 28 percent helium, with the remaining matter accounting for just 2 percent of its mass.
Over time, the hydrogen in the Sun's core turns into helium. Conditions in the Sun's core, which is 25 percent of its diameter, are extreme. The temperature is 15.6 million Kelvin and the pressure is 250 billion atmospheres. The energy of the Sun is achieved through nuclear fusion reactions. Every second, approximately 700,000,000 tons of hydrogen are converted into 695,000,000 tons of helium and 5,000,000 tons of energy in the form of gamma rays.
3) Our solar system
15*10 12 kilometers in diameter
Our solar system includes just one star, which is the central object, and nine major planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto, as well as many satellites, millions of solid asteroids and billions of icy comets.
4) Star VY Canis Major
The largest star in the universe (3 billion kilometers in diameter)
VY Big Dog It is the largest known star and one of the brightest stars in the sky. It is a red hypergiant located in the constellation Canis Major. The radius of this star is about 1800-2200 times greater than the radius of our Sun, its diameter is about 3 billion kilometers.
If this star were placed in our solar system, it would close the orbit of Saturn. Some astronomers believe that VY is actually smaller—about 600 times the size of the Sun—and therefore would only reach the orbit of Mars.
5) Huge deposits of water
Astronomers have discovered the largest and most massive reservoir of water ever found in the universe. The giant cloud, about 12 billion years old, contains 140 trillion times more water than all of Earth's oceans combined.
A cloud of gaseous water surrounds a supermassive black hole located 12 billion light-years from Earth. This discovery shows that water has dominated the universe for almost its entire existence, the researchers said.
6) Extremely large and massive black holes
21 billion solar masses
Supermassive black holes are the largest black holes in the galaxy, weighing hundreds or even thousands of millions of solar masses. Most, and possibly all, galaxies, including Milky Way, according to scientists, contain supermassive black holes at their centers.
One such monster, 21 million times the mass of the Sun, is an egg-shaped funnel of stars in NGC 4889, the brightest galaxy in the stretched cloud of thousands of galaxies. The hole is located about 336 million light-years away in the constellation Coma Berenices. This black hole is so huge that it is larger than ours in diameter. solar system 12 times.
7) Milky Way
100-120 thousand light years in diameter
Milky Way - crossed spiral galaxy, which contains 200-400 billion stars. There are many planets revolving around each of these stars.
According to some estimates, 10 billion planets are in the habitable zone, revolving around their parent stars, that is, in zones where there are all conditions for the origin of life like Earth.
8) El Gordo
The largest cluster of galaxies (2 * 10 15 solar masses)
El Gordo is located more than 7 billion light-years from Earth, so what we are seeing today is just an early stage of it. According to the researchers who have studied this galaxy cluster, it is the largest, hottest and emits the most radiation than any other known cluster at the same distance or further.
The central galaxy at the center of El Gordo is incredibly bright and has an unusual blue glow. The authors of the studies suggest that this extreme galaxy is the result of a collision and merger of two galaxies.
Using the Spitzer Space Telescope and optical imaging, scientists estimate that 1 percent of the total mass of the cluster is stars, and the rest is hot gas that fills space between the stars. This ratio of stars to gas is similar to the ratio in other massive clusters.
9) Our Universe
Size - 156 billion light years
Of course, no one could ever name the exact dimensions of the Universe, but, according to some estimates, its diameter is 1.5 * 10 24 kilometers. In general, it is difficult for us to imagine that there is an end somewhere, because the Universe includes incredibly gigantic objects:
Earth Diameter: 1.27*104km
Sun diameter: 1.39*106 km
Solar system: 2.99 * 10 10 km or 0.0032 sv. l.
Distance from the Sun to the nearest star: 4.5 sv. l.
Milky Way: 1.51*10 18 km or 160,000 sv. l.
Local group of galaxies: 3.1 * 10 19 km or 6.5 million sv. l.
Local supercluster: 1.2 * 10 21 km or 130 million sv. l.
10) Multiverse
One can try to imagine not one, but many Universes that exist at the same time. The multiverse (or the Multiple Universe) is an allowable collection of many possible universes, including our own, which together comprise everything that exists or can exist: the integrity of the cosmos, time, material matter and energy, as well as the physical laws and constants that describe it all.
However, the existence of other Universes besides ours has not been proven, so it is very likely that our Universe is the only one of its kind.
