How far away is the Big Dipper? How does it compare to the size of the sun?

The vast universe has always been full of curiosity for us, thinking that it is full of many mysterious and unknown things, so we have been trying our best to explore, and the vast universe is indeed unfathomable for us, only with the current level of human technology, it is extremely difficult to completely explore a corner of the universe, but we have also been unremittingly improving the technical level, I believe that one day we can solve the mystery of the vast universe, Look for planets and extraterrestrial civilizations that are full of mysteries to us, and even achieve interstellar travel. Although our ancients did not have various methods to explore the universe in those days, they would also use their own methods to explore the universe initially and satisfy their curiosity about the unknown thing in the universe. For example, the study of Xingdou has begun since the time of our ancients, and the most representative of them is the Big Dipper.

The Big Dipper is actually seven stars in the constellation Ursa Major from an astronomical point of viewWe know that our earth is in the solar system, and the natural light we feel during the day comes from the sun, a star that relies on nuclear fusion to continuously emit heat and radiation, which is the basis for the survival of our life, and the solar system is only one of the galaxies in the Milky Way, and there are many star systems in the Milky Way, and the Milky Way is only a small galaxy in the vast universe. In fact, 99% of the stars we see in the night sky at night are stars, and the Big Dipper is one of them.

It's not very far away from us, and it often appears in the northern sky, which can be seen with the naked eye. At the same time, these seven stars are independent celestial systems with a cycle of 800,000 years. The Big Dipper forms a bucket shape, so it's easy to identify.

And to know how far away the Big Dipper is, we must first know which seven stars are respectively, and the seven main stars of the Big Dipper are the brightest stars in the constellation Ursa Major: Alkaid, Mizar, Alioth, Megrez, Phecda, Dubhe, and Merak (corresponding respectively).Shaking Light Star, Kaiyang Star, Yuheng Star, Tianquan Star, Tianji Star, Tianshu Star, and Tianxuan Star

And the distance between them and our earth is of course also different, according to authoritative research, the distance between these seven stars and our earth is:Shake Light 101 2 light years, Kaiyang light years, Yuheng light years, Tianquan light years, Tianji light years, Tianxuan light years, Tianshu 124 2 light years。The Big Dipper is a constellation of seven stars, and each star is larger than the central star of the solar system, the Sun, in terms of volume, mass, luminosity and surface temperatureEquivalent to the times and times of the sun.

The Big Dipper is far away, and it may be on the other side of the galaxy. And the distance is still so bright, it is conceivable that the Big Dipper must be several times stronger than the sun.

The distance between the Big Dipper and the Earth is not the same, the nearest one is several times the distance from the Moon to the Earth, and the farthest one is more than ten times, which is still a little smaller than the Sun compared to the Sun.

The Big Dipper is actually a star, quite far away from us, not visible to our human eyes, it should be a planet outside the solar system, theoretically far larger than the solar system.

The Big Dipper are stars, not the stars we see, so they are planets outside the solar system, and they are generally larger than the mass and volume of the sun, and their lives may have come a long way and have entered the end of Hang Seng life.

The Big Dipper is still relatively far away from the earth, so it can be said that the moon is relatively close to us. So you can infer from this distance, these planets are also much smaller than the sun, because the sun is a big sphere.

How far away, a person will not be able to reach the fighter in his lifetime, listen to him bragging.

The Big Dipper. Located in the constellation Ursa Major, the Big Dipper can be spotted in the night sky of the Northern Hemisphere almost every day under good observation conditions, and the seven bright stars form a unique spoon shape that is easily recognizable. In places with good observation conditions, there are more than 2,000 stars visible to the naked eye in the night sky.

There are more than 7,000 stars visible to the naked eye throughout the Earth, including the Big Dipper in the northern sky. The hand hides the answer that water, metal, fire, wood, and earth are our solar system.

Planets, like the Earth, revolve around the Sun.

As the only known star in the solar system, the Sun accounts for the total mass of the solar system, and its strong gravitational pull determines the motion of the planets. Except for the five planets, all the stars in the night sky are actually stars, and Bi Hui, the Big Dipper, is also a star. Since they are stars, they can go through nuclear fusion.

Releases light and heat. Not only that, but most stars have planets around them, like our sun. Yao is a very young star, only 10 million years old, while our Sun is 4.6 billion years old.

The star is light-years away from the Earth, has a mass twice that of the Sun, and is 594 times brighter than the Sun. If the Sun were replaced with Kony light, the Earth would be scorched and the habitable zone would migrate 3.6 billion kilometers, roughly on Uranus.

outside the track. Astronomers discovered that Kaiyang Star.

Not a simple binary star system.

Rather, it is a rare six-star system. There is a smaller star nearby, forming a binary star system. There are also three stars near Kaiyang, forming a quadrilateral.

System. These six stars in turn combine with each other under the influence of gravity to form a larger star system.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

The Big Dipper is very large. The Big Dipper is like the sun, but it is twice as massive as the sun. It is a very massive star, which is fainter than the fiber cover, and is about light-years from Earth.

The seven stars of the Northern Qing Dynasty are very large, the mass is twice that of the sun, they are very far from the earth, and we only see a little bit in our eye book, about 82 light years.

The mass of the Big Dipper is twice that of the Sun; Light-years from Earth,

The Big Dipper is about 6 times larger than the Sun and has a lot of mass. The distance from Earth is light years.

The Big Dipper is particularly massive, larger than the Sun. The distance from the Sun is light years, and the Big Dipper is a 6-star system.

The seven stars of the Big Dipper are all stars in the Milky Way, they can only be seen by others in the north, about 124 light years away from us, and the position of the Big Dipper will also change with the seasons and seasons, which is very peculiar.

The Big Dipper is made up of 7 stars, Argyrus, Abecda, Abecda, Yuheng, Kaiyang, and Waxing, which are 70 light-years away from us, and 124 light-years away.

The Big Dipper is made up of seven stars, shaped like a spoon, about 80 to 100 light-years away from us, and each star is at a different distance from us.

The Big Dipper is a star that we are very familiar with. It is located in the northern sky and consists of seven stars, shaped like a bucket used to scoop wine in ancient China, so it is called the Big Dipper.

What are the names of the seven stars that make up the Big Dipper? Also from the end of the bucket body to the end of the bucket handle are Tianshu, Tianxuan, Tianji, Tianquan, Yuheng, Kaiyang, and Shaoguang. The details are shown in the figure below.

So what kind of stars are the Big Dipper? Who are they bigger than the sun? Let's start with the first star of Doukou, Tianshu, and introduce them one by one.

The Celestial Pivot is located approximately 124 light-years from Earth. It is the farthest of the Big Dipper from Earth. Tianshu is the second brightest star in the Big Dipper, with an apparent magnitude.

The mass of the Tianshu is four times that of the Sun, with a diameter of about 44.54 million kilometers, which is also 32 times the diameter of the Sun. It is more than 30,000 times larger than the Sun. So the Celestial Pivot is an expanding orange giant star with a surface temperature of about 4400, which is much lower than that of the Sun.

It has come to the end of its life.

Sky Swirl is the second star from Doukou. It is located about 79 light-years away from Earth. The magnitude is bright.

Sky Swirl is a main-sequence star with a mass 3 times that of the Sun, a diameter of about 2 times that of the Sun, and a surface temperature of about 9500. Its surface temperature is much higher than that of the sun.

Dimensity is the third star from the Doukou. It is located about 83 light-years from Earth. Magnitude brightness.

The mass of the celestial star is 3 times that of the Sun, and the radius is also 3 times that of the Sun. Its surface temperature is about 9000. It is a main-sequence star much larger than the Sun.

Tianquan Star is also known as Composition Quxing in ancient China. It is located about light-years away from Earth. The magnitude of the star is bright, and it is the faintest star of the Big Dipper.

The mass of Tianquan is times that of the sun, the radius is times that of the sun, and the surface temperature is about 8600 9800. The planet Celestial Power is slightly larger than the Sun.

Yuheng is the first star in the Big Dipper. It is located about light-years away from Earth. It is the brightest star of the Big Dipper. The mass of Yuheng is about 3 times that of the sun, the radius is about 4 times that of the sun, and the surface temperature is about 8700.

Kaiyang is the second star of the Big Dipper, which is also called "Wuqu Star". It is located about light-years away from Earth. The magnitude is equal in brightness. It has 2 times the mass and radius of the Sun.

Yaoguang is the star at the very end of the Big Dipper. It is located about 104 light-years from Earth. Yaoguang regards the magnitude of the star as.

It has 6 times the mass of the Sun and a radius about twice that of the Sun. It is a blue main-sequence star with a very high surface temperature of about 14000 to 16000. Scientists have observed that the age of Yaoguang Star is only about 10 million years old.

The above are some basic facts about the seven stars of the Big Dipper. Of the seven stars, the Celestial Pivot is the farthest and largest from Earth. Yaoguang is the most massive star with the highest surface temperature.

Kaiyang is the closest one to the earth. Tianquan is the smallest star. However, even the smallest celestial power is larger in mass and volume than the sun.

They are all small stars, these stars are relatively large, and these 7 stars are all larger than the Sun. Generally multi-star systems.

The Big Dipper are stars located in other constellations, and they are similar in nature to the Sun, but differ in size from the Sun. They are all larger than the sun.

The Big Dipper are stars that are closer to Earth and younger than the Sun. Compared to the Sun, these stars are relatively large.

The distance from Earth also varies from 78 light-years to 124 light-years. The Big Dipper, just like the sun, is also a very massive star, and the Big Dipper actually refers to the seven planets of the Big Bear, such as Tianshu, Tianxuan, Tianji, Tianquan, Yuheng, Kaiyang and Shaoguang. The distance from Earth also varies from 78 light-years to 124 light-years, and the Big Dipper, like the Sun, also belongs to the stars.

Its mass is greater than that of the Sun, ranging from 1 5 times to 6 1 times that of the Sun. The Big Dipper is an ancient person who connected these seven celestial bodies when observing the starry sky.

Because it resembles the barrel shape of an ancient sake spoon, it was named the Big Dipper. Since ancient times, the Big Dipper has had a special meaning in China, which of the seven Big Dipper is the largest, Tianshu is a star who has evolved into a star in the era of the Red Star. At the moment it has expanded to 22 8 times the diameter of the sun.

Judging by its size, it has the largest diameter, and the Sun is also a star, which is more lonely compared to the Big Dipper, since most of the Big Dipper is a binary or multi-star system.

For example, Kaiyang is a six-star system, while Tianquan is a three-star system, only Shaoguang, Tianquan and Yuheng are single stars, looking up at the stars at night, most of the stars visible to the naked eye are stars, and only a few of them are planets in the solar system. These stars surround the Milky Way's solar system, ranging from a few light-years to hundreds of light-years. We know that stars are the main energy sources in the universe and are mainly composed of hydrogen and helium.

Because these stars collapse due to the collapse of their own gravity, the core of the star will undergo hydrogen nucleus fusion, releasing a huge amount of energy. The intensity of nuclear fusion is directly related to the mass of the star. The greater the mass of the star, the faster the nuclear fusion and the shorter the lifespan, all we need to do is know that the Sun is just a very ordinary member of the Milky Way in the universe, even though it is the absolute leader of the solar system.
