How many stars are a sun?

16, one sun is equal to 4 moons, and one moon is equal to 4 stars.

Most of the stars that can be seen in the sky are stars, and the size of the stars varies greatly, some are giants, some are dwarfs. The diameter of the Earth is about 13,000 kilometers, and the diameter of the Sun is 109 times that of the Earth. Giants are the largest in the star world, and they are tens to hundreds of times larger than the Sun.

Supergiants are even larger, with the red supergiant Antares (i.e., the constellation Antares) being 600 times the diameter of the Sun; The red supergiant Betelgeuse (Orion) is 900 times the diameter of the Sun, and if it were in the Sun's position, it would be almost as big as Jupiter. They are not yet the largest, VV the constellation Cepheus is a pair of binary stars, and its host star A, which is 1600 times the diameter of the Sun; HR237 is 1,800 times the diameter of the Sun. There is also a binary star called Pillar One, whose companion star is larger than the main star, 2,000-3,000 times the diameter of the Sun.

These giants and supergiants are giants in the stellar world. Now that we've seen the giants in the stellar world, let's take a look at the gnomes among them. In the stellar world, the Sun is medium in size, and there are many stars smaller than the Sun, the most prominent of which are white dwarfs and neutron stars.

White dwarfs are only a few thousand kilometers in diameter, about the same as Earth, and neutron stars are even smaller, they are only about 20 kilometers in diameter, and both white dwarfs and neutron stars are dwarfs in the stellar world. We know that the volume of a sphere is proportional to the cube of the radius. If we compare the volume, the column one mentioned above is more than 9 billion times larger than the Sun, and the neutron star is hundreds of trillions times smaller than the Sun.

This shows how different a giant is from a dwarf.

The stars in the sky are very large. Most of the stars we can see are stars, and Changxing is about the size of the sun. It's many times bigger than the Earth.

Most of the stars we see at night are stars, and most stars are much larger than Earth.

For example, the Sun is a star, 1.3 million times larger than the Earth. But the Sun is also just an average-sized star, and there are many stars that are larger than the Sun.

Therefore, it can be said that most of the stars in the sky are larger than the earth.

The stars in the sky are actually asteroids in the universe, with different sizes

The stars you can see are basically stars in the sky, and they're all as big as the sun, or even bigger.

The stars in the sky are big and small, and the stars we see when we look up at the sky at night are basically stars, and their volume is generally larger than that of the earth, or even much larger, but they are very far away from us and look relatively small.

Stars in the universe are large and can be up to 600 times the radius of the Sun (the radius of the Sun is about 696,300 kilometers), while the small ones are not visible to the naked eye. Because at the end of star decline, it will continue to collapse towards itself due to its own gravitational relationship, and it will collapse to the size of only atoms and even neutrons. However, it has a very high density and mass, and some of it even emits light, which is observed by humans.

Stars refer to celestial bodies in the universe that are visible to the naked eye. The activity of the energy inside the star makes the star irregularly shaped. Stars can be broadly divided into planets, stars, comets, white dwarfs, etc.

The brightness of a star is often expressed in terms of magnitude. The brighter the star, the smaller the magnitude. The brightest planet is Venus, the fastest star orbiting at more than 240 kilometers per hour, and h1504+65 is the hottest white dwarf.

Related information. The activity of the energy inside the star makes the star irregularly shaped. However, the stones of a high mountain are rolled down from a high place by the gravitational pull of the stars (gravitational pull), and the rivers carry sediment from a high place to the low-lying ocean (rivers also flow by the gravitational pull of the stars) These are all examples of concentration towards the center, and they all make the stars irregularly spherical.

If the interior of the star ceases to move, it is possible that after many billions of years, the star will become a very standard spherical shape (except for centrifugal force and the gravitational pull of other celestial bodies). Many asteroids, due to their relatively small mass, lead to their own gravitational force is relatively small, and the star is generally composed of relatively hard solid rock, it is difficult to complete the process of moving to the center under the action of its own gravity.

It is very large, and it is estimated that more than 99 percent of the stars are more than 1 million kilometers in diameter.

Twinkle and twinkle, the sky is full of little stars hanging in the sky to put light, just like beautiful little eyes, twinkle and twinkle, the sky is full of little stars hanging in the sky to put light as if many small eyes are twinkle and shiny, the sky is full of little stars (make up the number of words) bigger than you think.

The Sun is a star.

The sun is the central body of the solar system and occupies the overall mass of the solar system. The eight planets in the solar system, asteroids, meteors, comets, outer Neptune objects, and interstellar dust all revolve around the Sun, which revolves around the center of the Milky Way.

The Sun is a star located at the center of the solar system, and it is almost an ideal sphere intertwined with hot plasma and magnetic fields. In terms of chemical composition, about three-quarters of the mass of the Sun is now hydrogen, and almost all of the rest is helium, including oxygen, carbon, neon, iron, and other heavy elements with less than 2% of the mass, which uses nuclear fusion to release light and heat into space.

The Sun is currently passing through the local interstellar cloud in the local bubble of the Orion Arm at the inner edge of the Milky Way. At a distance of 17 light-years from Earth, there are 50 of the closest star systems (the closest star to the Sun is a red dwarf called Proxima Centauri, about light-years).

The mass volume of the Sun

The Sun is a huge, hot planet of gas. Knowing the distance between the sun and the earth, and then measuring the angle diameter of the sun's circle from the earth's Ming Xun sphere, we can find that the radius of the sun is 10,000 kilometers, which is 109 times the radius of the earth. From this, it can be calculated that the volume of the Sun is 1.3 million times that of the Earth.

According to Kepler's third law of planetary motion, astronomers can also calculate that the mass of the Sun is kilograms, which is 330,000 times that of the Earth, using the mass of the Earth and the radius and period of its orbit around the Sun. And concentrates the mass of the solar system.

From the volume and mass of the Sun, it can be calculated that the average density of the Sun is gram centimeter3, which is about a multiple of the average density of the Earth. The gravitational acceleration on the surface of the Sun is equal to 2 meters and seconds, which is about 28 times the acceleration of gravity on the Earth's surface, and if a person were standing on the surface of the Sun, he would weigh 20 times as much as he would be on Earth.

In terms of volume, stars are generally larger than the sun.

Stars and the sun are both stars, but the sun is close to the earth, so they think that the sun is bigger, in fact, most stars (that is, the stars) are much larger than the sun, even tens of millions of times larger than the sun, hundreds of millions of times larger.

It's just that the stars are far, far away from human beings, and the reason that the stars are small and small.

Classification of stars.

1. According to the type: stars, planets, satellites, dwarf planets (this classification is only in the solar system), small celestial bodies (asteroids, comets, etc.).

2. According to the stage: novae, main sequence star, red giant, supernovae (divided into the following white dwarf stars, neutron stars, black holes).

3. According to size: (maroon-red) dwarfs, (blue, blue-white, yellow, red) giants, (blue, red) supergiants.

4. According to the spectrum: O, B, A, F, G, K, M and additional types such as R, N, S, etc.

5. According to the combination: single star, double star, star cluster and star cluster.

6. Other classifications: non-variable stars, variable stars. Variable stars are divided into: Cepheid variables, eclipse variables.

The Sun is just the largest in the solar system.

The nine planets are in order: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto.

The so-called "nine planets" of the solar system are a popular term in history, namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.

Pluto was designated as a dwarf planet and named asteroid 134340 at the 26th International Astronomical Union (IAU) in Prague on 24 August 2006. So now there are only eight planets in the solar system.

Definition of planets given by the 2006 International Astronomical Congress

One is that it must be a celestial body orbiting a star.

The two-state Zen land is massive enough to rely on its own gravitational pull to make the celestial body spherical.

The third is that there should be no other celestial bodies in the vicinity of their orbits, or they can "clean" themselves in orbit within 3 billion years.

Pluto is at odds with the third, Pluto's orbit intersects with Neptune (arguably, if this is the case, then Neptune also crosses Pluto's orbit), and there are several other objects in the solar system that are roughly equal in size to Pluto.

The Sun is the central star of our solar system, and it far surpasses other stars in size and mass. However, it is true that there are stars in the universe that are larger than the Sun, and these stars are known as supergiants or supergiants. They are much larger and more massive than the Sun, making the Sun appear relatively small in comparison.

However, such supergiants are rare in the entire universe of Ashishin. Based on our current observations and understanding, it is estimated that there may be only a few hundred or fewer supergiants in our galaxy.

One of the most well-known supergiants is the Cygnid VY star, which is considered to be one of the largest stars currently known. Its diameter is estimated to be about 1,600 times larger than that of the Sun. There are other known supergiants, such as Vx Leo and V483 Canis Major, which are also recognized as extremely large stars.

It is important to note that due to the vastness and complexity of the universe, there is still much to be discovered and studied about what we know about the stellar chakra. As a result, scientists are constantly making observations and researches in an effort to expand our knowledge of the stars in the universe.

According to the current observations and research of Burning Socks, there are about thousands to tens of thousands of stars larger than the Sun. These large stars may be supergiants, supernovae pikeys, or other types of stars that play an important role in the universe. However, this is only an approximate estimate, and the exact number may change as science progresses.
