How many stars are in the sky 5, how many stars are in the sky

It depends on how you want to see it, if it's naked, that is, you can see it with the naked eye, if the weather is favorable, you can see about 6,000 pieces, and some people with super good eyesight can see about 8,000 pieces. But if you want to say that you want to look at it with the star map, then you have to know how many stars there are in the universe, not to mention anything else, there are more than 200 billion stars in the Milky Way galaxy where we live now, which is what you call stars. There are nearly 100 billion galaxies in the universe, which have been discovered by human beings, not including places that are not up to the mark in science and technology, and some asteroids produced by some white dwarfs that are often the best.

Don't ask me how many stars there are, I'll tell you a lot ... A lot...

A man with good eyesight (let's say, he can see stars of equal brightness) on a clear moonless night, and counts the stars in the sky that he can see (regardless of how he counts), will find that there are about 3,000 stars in the sky.

As for how many stars there are in the entire universe, that's an estimated number.

It is more credible to say that there are about 170 billion galaxies in the (observable) universe, and each galaxy has a few tens of millions or trillions of stars, so that the number of stars in the universe is tens of billions (10 18, 1 followed by 18 zeros) to quadrillion (10 23, 1 followed by 23 zeros). This does not include the number of planets and other celestial bodies that look like stars. So it's true to say that there are many, many stars in the sky.

Count how many hairs you have.

People always say that there are too many stars in the sky, but in fact, all the stars that can be seen with the naked eye can still be counted. 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.

How much do you know about the starry sky.

About 3 after 23 zeros.

Peter of the American astronomer at Yale University. 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.

The vastness of the universe. There are countless galaxies. Counting the stars is a very romantic thing, and then ang. Actually, I think many stars are well known, but how many stars there are. It depends on how much you feel in your heart.

It's good to count the stars under the stars, but you can only count the moon.
