How many stars there are and how many stars there are

Nearly 7,000 stars are visible to the naked eye throughout the day, but the earth is spherical, so at most more than 3,000 stars can be seen with the naked eye at any one time. There are about 100 billion to 200 billion stars in the Milky Way that are the same as the Sun. Hundreds of billions of extragalactic galaxies have been discovered.

In the end, I'm afraid no one can be sure.

There are about 6,973 of them, but there are 700 billion of them.

Stars are made up of an infinite number of planets. The stars are also hearts. Can't count,

What is this called me, there are countless stars in the universe that are being born, and it is impossible to count them at the moment.

You ask me how many stars there are, and I say there are innumerable!

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.

Many, many, too many to count.

First, the Milky Way alone has between 100 billion and 300 billion stars, and there are at least 100 billion galaxies in the universe that resemble the Milky Way. Add to that undiscovered galaxies and the stars that roam between them, and that's a huge number.

Secondly, there are not only stars in the universe, but also quasars, planets, moons, comets, and so on. More than half of the stars have at least one planet. While the jury is still out on whether other galaxies have moons, asteroids, and comets, the protoclouds of the solar system alone have at least 10 comets, and the number of asteroids in the solar system is at least 500,000.

There are more than 6,000 stars visible to the naked eye, and there are only countless invisible to the naked eye, because at present, human beings can only observe the universe with a radius of less than 200 light years, and there are many stars that human beings have not seen!

The average person can see more than 6,000 stars with the naked eye. With the help of telescopes, hundreds of thousands or even millions of them can be seen. It is estimated that there are about 1500-200 billion stars in the Milky Way.

Countless.

Is it heavenly or Zhang Jie's fan.

On moonless nights, people with good eyesight can see more than 3,000 stars, most of which are stars. With the help of a telescope, the number of stars that can be seen increases exponentially.

The Milky Way, where our sun is located, includes about 30000000000000 stars (stars), and there are about 10 trillion observable galaxies like the Milky Way in the universe, and this is not the whole universe. So, the number of this star can only be described as innumerable.

The apparent magnitude of a star visible to the naked eye is about 6.

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.

Hope it helps!

Don't be so obsessed with counting the stars, you just need to know that there are no stars on a rainy night, no, there are some things that can't be represented by data, but you can count them yourself, hehe.

If you can tell me how many water molecules there are on Earth, I'll tell you how many stars there are.

Many, many, unknown.

You can do the math: the Milky Way is estimated to have at least 100 billion stars, and about 100 billion galaxies have been observed in the universe so far (each equivalent to a galaxy, or even larger than the Milky Way). In addition, most of the stars in the universe have at least one planet.

In addition to this, there are also moons, asteroids (there are at least a million asteroids in the solar system), comets (there are at least 10 comets in the protoclouds of the solar system alone), and so on.

How many stars are there in the universe?

There are about 125 billion galaxies that have been discovered and observed, and each galaxy has hundreds to trillions of stars like the Sun. Our galaxy is home to about 40 billion planets. So with a simple math problem, it's not hard to understand that there are many, many stars in the universe that we've observed.

The total number of planets in the universe is about 1 trillion (1 followed by 20 zeros).

You can take a look at mine below to see if it's clear.

There are as many stars as there is dust on the field around your house, and there are countless stars.

The exact number is known only to God, for it was all created by his old man.

Roughly do the math. In addition to one star, eight large planets and the moons carried by these planets (none of which contain artificial bodies), the number of asteroids in the solar system is estimated to be about 200,000, and the number of Oort clouds and Kuiper belt objects is unknown, but not less than the number of asteroids.

There are about 10 million 20 million stars in the Milky Way, and there are about 10 million 20 million galaxies similar to the Milky Way in the observable universe.

Multiply that and that's the total number of stars in the currently observable universe.
