How small is the earth?

Isn't it said that there are galaxies in the universe that are many thousands of miles larger than the Milky Way? The earth is a speck of dust!

The Earth is very small, and he is also ranked in the bottom few in the Milky Way, and after leaving the Milky Way, he basically can't see the existence of the Earth.

The Earth is located in the Milky Way, and the Milky Way has a very large space in which it contains many planets, and from the Milky Way, the Earth is just a point in it.

Because the universe is very vast, there are many planets in the universe, and they are all very large, while the earth is very small. So the earth is very small.

The earth is very small in the universe, and when human beings explore alien planets, they find that the world outside the earth is very large, and the earth is only a small planet in this vast universe, and it is very small. In the universe, there are actually a lot of planets that are much larger than the earth. In the solar system, there are also several planets that are larger than the Earth.

The Earth's equatorial radius is about 6,378 kilometers, ranking fifth among the eight planets. Neptune's radius is about 24,788 kilometers, which is twice that of Earth; Uranus has a radius of about 25,559 kilometers, which is four times the size of Earth; Saturn's radius is about 60,268 kilometers, which is twice that of Earth; Jupiter is the largest planet in the solar system, with a radius of 71,492 kilometers, which is twice the size of Earth; The Sun is the largest celestial body in the solar system, with a radius of 10,000 kilometers, which is 109 times the radius of the Earth, from which it can be calculated that the volume of the Sun is 1.3 million times that of the Earth. From here, it can be seen that the earth is only a small thing in the solar system, and how does it compare to other larger planets in the universe?

In the universe, the solar system is only a part of it, and the sun is just a very ordinary star, and there are many planets that are much larger than the sun.

The brightest star in the night sky, Sirius, is slightly larger than our Sun, equivalent to a time the radius of the Sun, or 187 times the radius of the Earth if compared to the Earth. It can be said that it is very large, but in the universe, Sirius is only a relatively small planet, and there are many bigger than it.

The planet Gemini, known as Pollux, is much larger than Sirius, light-years away, equivalent to a multiple of the radius of the Sun and 960 times the radius of the Earth. The Earth, or the Sun, in front of it, is already quite small. Of course, this is not the largest celestial body in the universe.

About 36 light-years away, Arcturus is the brightest star in the constellation Pasturius and the brightest star in the night sky in the northern sky. The radius is 21 times that of the Sun, and if compared to the Earth, it is 2,289 times the radius of the Earth. The earth is in front of it, already small.

Of course, there are celestial bodies in the universe that are larger than Arcturus.

The Earth is almost a speck of dust in the universe, and when we have not explored outer space, the Earth is very large in our eyes, with a radius of more than 6,300 kilometers, and the Earth is inhabited by so many people and so many countries. When we began to understand outer space other than the Earth, we realized how small the Earth is in the universe.

Galaxy. There are at least hundreds of billions of motes like the Earth. After leaving the Milky Way, there are at least hundreds of billions of galaxies.

Each of them contains hundreds of millions of fine dusts. If the universe were infinite, then the earth would be only one of the infinite motes in the universe.

Volume: The Earth's equatorial radius is kilometers, the polar radius is kilometers, the average radius is about 6371 kilometers, and the equatorial circumference is about 40075 kilometers.

The Earth's surface area is 100 million square kilometers, of which 71% is oceans and 29% is land. Atmosphere.

The main components are nitrogen and oxygen and a small amount of carbon dioxide.

argon, etc. The Earth's interior is divided into the Earth's core.

The structure of the earth's mantle and crust, and the outer part of the surface has a hydrosphere and atmosphere.

and magnetic fields. The Earth is the only celestial body in the universe where life is known, and it is home to millions of living beings, including humans.

The earth has undergone 4.6 billion years of evolution, and it is this long time that has carved its unique appearance and given birth to unique life.

So why is the earth small?

The answer is revealed below.

The circumference of the Earth's equator is about 40,075 kilometers, and the walking speed of an average person is about 4,500 m h, which means that if you walk around the equator without stopping, it will take about 371 days.

In fact, this 'hugeness' is only for human beings, if you look at the whole universe, then the earth will be like a grain of sand (maybe not as good as sand), its volume will be inconspicuous!

In 1608, the world's first telescope was built in the Dutch optian-dealer Hanslippershey

Born in the hand, after that, the eyes of human beings are more and more distant.

After more than 400 years, today's human eyes have crossed the mountains, broken through the earth, and stepped into space.

At present, human beings generally believe that the radius of the solar system is 40 astronomical units, about 6 billion kilometers (bounded by the orbit of Pluto), which is equivalent to the length of 470,000 Earth's flat on the same plane, and then exaggerated, for example, if you keep walking, it will take about 150,000 years, which is equivalent to making the recorded human history restart more than 30 times!

Does this set of data surprise you?

Let's move on to the data from the following set.

The current observable diameter of the universe is about 93 billion light-years!

This means that light emits from one end of the currently observable end, and if it is not affected by other stars, it will take 93 billion years to reach the other end!

This time is so long that it makes no sense to humans.

Compared with the universe, it is no exaggeration to say that the earth is like sand and gravel floating in the ocean, and I don't know where it comes from or where it goes!

Question 1: Look at how small the earth is in the universe Hundreds of billions of earths are equal to one sun, hundreds of thousands of suns are equal to solar systems, thousands of solar systems are equal to the Milky Way, thousands to tens of thousands of galaxies are equal to one galaxy, and unfamiliar galaxies are only 5 percent of the universe

Question 2: How small is the earth to Li Hudi The earth is very large, relative to us human beings.

The Earth is tiny, relative to the entire galaxy, the entire universe, the entire world.

The Earth is the equivalent of a piece of sand in the Milky Way, as small as you can imagine.

Question 3: How small is the earth The earth is really a speck of dust in the universe, not even a speck of dust! Because the earth is really too small in the universe, so small that it is indescribable!

The earth is quite large for us humans, but the volume of the earth is only 1.3 million times the size of the sun. And our Sun is just a very ordinary star in the Milky Way, and there are hundreds of billions of stars like the Sun in the Milky Way. And the Milky Way is 100,000 light-years in diameter!

The Milky Way is unimaginably large for humans, but so far humans have discovered billions of extragalactic galaxies as huge as the Milky Way! Think about how big the universe is, isn't it unimaginably big? Can't imagine?

Through the above comparison, you can feel how big the universe really is. How small the earth is!

Question 4: How small is the earth in the universe The earth is really a speck of dust in the universe, not even a speck of dust! Because the earth is really too small in the universe, so small that it is indescribable!

The earth is quite large for us humans, but the volume of the earth is only 1.3 million times the size of the sun. And our Sun is just an ordinary star in the Milky Way.

Question 5: The earth is small, and the earth is great and beautiful. (changed to an exclamation sentence). Emphasis on the previous clause: Emphasis on the latter clause: 20 minutes Emphasis on the previous clause: The earth is small, although it is so great and beautiful.

Emphasize the latter clause: Although the earth is small, it is great and beautiful.

Question 6: Why is the earth small in the vast universe "Small" means "insignificant", from this sentence we understand that "size is a relative concept, and the results of comparison will be very different if the reference objects are different".
