Who knows how many stars there are in the sky? How many stars are there in the sky?

There are around 6,000 stars visible to our naked eye. But only a small part of the universe.

An astronomy team at the Australian National University concluded through calculations that there are 70,000,000,000,000,000,000,000,000 (7 after 22 0, 7 trillion trillions) stars in the universe. Such a huge number could be more than all the grains of sand on all the deserts and beaches on the planet.

The team demarcated a region of the sky and counted the brightness of about 10,000 galaxies in between, to determine the number of stars in them. Such a statistical method avoids the tedious process of counting each star. The number of stars in the entire universe is then obtained by multiplying the number of stars in the entire universe by multiplying the number of stars in the entire sky and this strip-shaped region.

There are about 7,000 stars in the sky that can be seen with the naked eye, while people can see half of them in the same place, more than 300. The words of the telescope are too many to count, because the telescope will become more and more advanced.

If there are about 6,000 stars that can be seen clearly with the naked eye, there are many more that cannot be seen, and with the advancement of technology, more and more stars are found.

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

There are as many drops of water as there are grains of sand on the ground.

There are as many drops of water as there are in the universe in the universe.

As much as the sand on the earth, count it yourself...

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.

The stars we usually see above are the stars of the Milky Way, and the number of stars in our galaxy is about 500 billion. So on the other hand, the number of stars in our sky is generally about 600 billion that can be observed with the naked eye or ordinary telescopes.

Dear landlord, it is a pleasure to answer your questions. In total, there are 6,974 stars visible to the naked eye, but there are many more invisible stars in the universe, and the total number of stars is about 10 24.
