How many stars are there in the sky as the title Thank you

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 of them.

Want to know how many stars there are in the sky? Very simple. I'm going to tell you that first, you have to figure out how big the universe is, then you have to figure out how many galaxies there are in the universe, and then you have to figure out how many stars there are in each galaxy on average (10e to be sure), and then you multiply the number of galaxies by the number of stars in each galaxy, and that's it.

Isn't it easy?! Convenient?

The total number of stars we can see with our eyes is 6,974.

A lot of hair, as many stars as there are in the sky.

Not much, you count how much sand there is on the earth, and there are more stars than sand.

There are as many stars in the sky as there is sand in the desert!!

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

There are about 100 billion (star) stars in the Milky Way. 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.

There are about (or known) about 1,000 billion lines.

There are 12 dimensions of space-time in the universe. The balance of human beings exists in 3-4 dimensional space-time. (Stars in different time and space do not collide).

6974 pieces. The total number of stars we can see with the naked eye is 6,974 without instruments, but since we only see half of the starry sky and cannot see the starry sky on the other side of the earth, we can only see about 3,500 stars. If you want to see the other 3,000 or so, you'll have to run to the other side of the world.

With the help of instruments such as astronomical telescopes, then there are countless stars, of which our galaxy has 200 billion stars, and there are countless galaxies like the Milky Way in the universe.

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

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

In terms of the number of stars that can be seen by the naked eye, there are no more than 7,000 in total. And since people standing on Earth can only see half of the sky overhead, we usually see only about 3,500 stars.

Everyone knows that the stars in the sky are bright and dark. As early as more than 2,000 years ago, astronomers lined up the stars according to their brightness, calling the brightest ones "1st magnitude stars" and the less inferior ones "2nd magnitude stars", "3rd magnitude stars", ......The faintest star that can be seen by the naked eye is a star of magnitude 6. In fact, in the entire sky, there are only 20 stars of the 1st magnitude, 46 stars of the 2nd magnitude, 134 stars of the 3rd magnitude, 458 stars of the 4th magnitude, 1476 stars of the 5th magnitude, and 4840 stars of the 6th magnitude.

From the 1st magnitude to the 6th magnitude stars, there are 6,974 in total, and even if you add Mercury, Venus, Mars, Jupiter, Saturn and other planets and the Sun, it is only 6,980.

Of course, this is limited to the stars visible to the naked eye, not the actual number of stars in the sky.

The actual number of stars in the Hand Universe is indeed an astronomical number. You just have to look at it with a telescope. The number of stars in a telescope is exponentially greater than what can be seen with the naked eye, and the larger the telescope used, the more stars can be seen.

For example, a small binoculars can see about 7 or 8 magnitude stars; 14th magnitude stars can be seen with a 120 (lens diameter of 120 mm) telescope manufactured by Nanjing Astronomical Instrument Factory; If you use the 5-meter telescope on Palomar Mountain in the United States, you can see 21 magnitude stars, which is about to be nearly 2 billion.

In fact, even if you use an astronomical telescope with a diameter of 5 meters to observe the stars, you can only see a drop in the ocean. The stars in the vast universe are actually innumerable. The Milky Way, where our Sun is located, is generally estimated to contain 1 5 lo", or about 150 billion stars, and dozens of such "Milky Way" have been observed by human observation methods today.

Everyone knows that what is "observed now" is far from the whole universe. Therefore, in this sense, the stars in the sky are indeed uncountable.

No one (including astronomers) can determine how many stars there are in the sky, only that there are countless stars in the sky; No one can be sure how many stars there are in the sky; Stars include stars, comets, planets, moons, and black holes. Because mankind has not yet been able to determine how many planets, comets and asteroids and planetary moons there are in the solar system. Humans still can't determine how many black holes, stars, and how many planets, comets, moons, and so on are in each star system. However, the stars that can be observed with our eyes are:

There are 20 first-magnitude stars, 46 second-magnitude stars, 134 third-magnitude stars, 458 fourth-magnitude stars, 1,476 fifth-magnitude stars, and 4,840 sixth-magnitude stars, for a total of 6,974 stars. With the help of telescopes, more stars can be observed. Of course, if it's a sunny day, there is usually only one star in the sky, the sun; Occasionally, two stars can be seen, one is the sun and the other is the moon.

Hope it can help you and good luck.

Your question cannot be answered, because there are stars that are born and dying at any time, and this exact value is changing at any time and we don't yet know how big the universe really is, and there are many kinds of stars you are asking, only stars are visible, and when we see them, because the distance is so far, the speed of light transmission is slower than that of a snail for this distance. So in our eyes they have just been born, but in fact they have long since died.
