How many stars are there in the sky, how many stars are there in the sky?

On a clear night, when we look up at the sky, we will see dense stars all over the sky, can we count the twinkling stars with the naked eye? There are more than 6,900 stars in the sky that can be seen with the naked eye. However, because it is at night, only half of the sky can be seen, so only about 3,000 can be seen with the naked eye on the earth.

Due to the dazzling lights of the city at night and the air pollution over the city, we cannot see many stars far away from the earth, and we can only see 1,000 stars. If you look at the stars with an astronomical telescope, the situation is different, and you can see about 1 billion of them. The universe is endless, and it is impossible to count the stars in the sky with the naked eye, and even the stars that astronomers see with telescopes are only a very small part of the stars in the universe.

Astronomers speculate that there are about 40 billion stars in the sky.

In the night sky, the stars twinkle in the sky, which makes us think about the question, how many stars are there in the sky? Can we count them all? Of course, the universe is infinitely large, and there are infinite stars in the universe.

And what we have to count are the stars that are visible to the naked eye and appear in the sky above the horizon. The stars can be counted. Astronomers divide these stars into constellations by region, and divide them into sixths according to their brightness, with the faintest visible to the naked eye being sixth.

As a result of this counting, there are a total of 6,974 angelic stars.

There are as many stars in the sky as there are grains of sand on the earth.

How wide the heart is! There are as many stars as there are.

At present, the exact number of stars in the sky cannot be determined.

The universe is infinite and there are infinite stars.

Some people say that it is able to see 6974 pieces.

Astronomers divide the stars in the sky into 88 constellations according to their regions. Among them, the northern sky (bounded by the celestial equator) has 29 constellations; There are 46 constellations in the southern sky and 13 constellations in the north and south of the celestial equator. As long as we have patience and count the stars in one constellation, we can count the stars that can be seen with the naked eye.

According to the calculations of astronomers: 6 stars of magnitude 0; 14 stars of 1st magnitude; 46 stars of 2nd magnitude; 134 stars of 3rd magnitude; 458 stars of 4th magnitude; 1476 stars of 5th magnitude; 4,840 ...... of 6th magnitudeNo more than 7,000 in total.

If we use a telescope, the situation is different, and even with a small astronomical telescope, more than 50,000 stars can be seen. The largest modern astronomical telescope can see more than 1 billion stars.

In fact, the number of stars in the sky is much more than that. The universe is endless, and what modern astronomers see is nothing more than a tiny, tiny part of the universe.

The total number of stars that can be seen with the naked eye is only about 6,000, and the number of stars seen through telescopes is much larger.

In addition, Peter of Yale University, an astronomer at the United States. Fan. Dokun and Charlie, an astrophysicist at Harvard University. Conroy analyzed the intensity of light from galaxies and concluded that there were far more red dwarfs in galaxies than previously thought.

Previously, astronomers estimated that the number of stars in galaxies was about a trillion times that of 100 billion.

Fan. After observing distant galaxies in Hawaii with the help of electron astronomical telescopes, Dokun and his team found that the stars of these distant galaxies were many times or even dozens of times larger than previously thought, and that the size of 3 was followed by 23 zeros. For the sake of the image, Conroy said that there are about 50 trillion human cells in each person and about 6 billion people on the earth, and the product of the two is exactly 3 followed by 23 zeros.

In other words, the stars in the sky are comparable to the total number of human cells on earth.

If you have a few hairs, there will be as many stars in the sky.

People always say that the stars in the sky are innumerable, in fact, all the stars that can be seen with the naked eye can still be counted, as long as we have patience, count the stars in a constellation, and then count the next constellation, we can count with the naked eye...

There are too many to count, and there is no constant number.

As many hair roots as all earthlings

It's too much to count.
