The solar system of the universe, how many solar systems are there in the universe?

The solar system consists of eight planets and their moons and more than 6,000 asteroid belts.

Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune. With thousands of asteroids, what more do you want to know?

Eight planets. Mercury, Venus, Earth, Mars, Saturn, Jupiter, Neptune, Uranus.

Mercury Venus.

Earth Mars. Jupiter Saturn.

Uranus Neptune in the solar system.

Dizzy, you just go directly to the encyclopedia. Why are you here to ask???

The solar system is so big, so big.

If we want to talk about "solar system", then there is only one solar system in the universe, and that is the planetary system in which we live.

But if there are planetary systems similar to the solar system, there are too many to count.

According to the current theory of star formation, stars and their planetary systems are created by gravitational collapse and condensation in a large cloud of interstellar gas. When the interstellar gas cloud begins its gravitational contraction process, it first shrinks into a large gas cloud and then gradually begins to rotate under the influence of a weak lateral force (possibly related to the Lorentz force). Due to the principle of conservation of angular momentum, as the gas cloud shrinks, the angular momentum gradually increases, the rotation accelerates, and the cloud gradually becomes flattened.

At this point, there is a differentiation of evolutionary processes.

Computer models show that if the mass is separated from the angular momentum at this point, a pair of binary (star) stars will be formed, and no planets will be produced on the periphery of the star.

If the mass and angular momentum are not separated at this time, a star will form in the center of the cloud and several planets will form in the periphery. This is the case in our solar system.

According to this theory, all individual stars may be surrounded by planets and planetary systems, all of which are identical or similar to our solar system.

In the Milky Way galaxy alone, about 25% of the stars are single stars, and the rest exist as binary stars, three-star stars, clusters, or star clusters. Well, probably all the individual stars have planetary systems similar to the solar system. The total number of stars in the Milky Way is between 200 billion and 400 billion, and the number of "solar systems" is at least 50 billion.

It's just that they're too far away from us, and the planets don't shine on their own, so we can't observe them.

In the observable universe, there are no less than 200 billion galaxies as huge as the Milky Way, and how many "solar systems" will there be?Probably an infinite number.

The universe is so big that there must be countless galaxies that resemble the solar system.

It's just that the current scientific and technological civilization of human beings has not yet reached that level, so the currently known quasi-solar system is still only our own solar system.

The universe is very big, and there are many galaxies like the solar system, but it's not just called the solar system!

1 There are about 2 trillion galaxies in the universe.

2 There is only one and only one solar system.

The specific solar system is only the one we are in.

If we refer to galaxies on the scale of the solar system, then we can think of it as infinite.

The universe is vast, and human beings have very limited understanding of it.

Looking up at the starry sky, we will find ourselves small. You will be able to see it.

So how many solar systems are there in the universe?We can tell now, and only the solar system we are in now. According to scientific reasoning, there must be more solar systems in the universe. But no evidence has been found.

In other words, there may only be one solar system in the universe, and you will eventually have only one Earth. But there may also be an infinite number of solar systems, with an infinite number of Earths.

There is only one solar system. The solar system includes the Sun, 8 planets, nearly 500 moons, and at least 1.2 million asteroids, as well as some dwarf planets and comets. If Neptune's orbit were used as the boundary of the solar system, the diameter of the solar system would be 60 astronomical units, or about 9 billion kilometers.

If bounded by the heliosphere, the Sun can be up to 100 astronomical units (at its thinnest) from the boundary of the solar system. If the Oort cloud is used as the boundary, the diameter of the solar system may be 200,000 astronomical units. The formation of the solar system began about 4.6 billion years ago with the gravitational collapse of a giant interstellar molecular cloud.

The Sun is located at the center of the solar system and is the closest star to Earth. It is located on the Orion Arm of the Milky Way, about 10 thousand parsecs from the heart of the galaxy. It is a red-hot light-emitting ball whose internal high temperature and pressure sustain nuclear fusion and thus provide a huge amount of energy.

The surface temperature of the sun is as high as 6,000 k, the temperature of the center is as high as 15 million kai, and the diameter of the sun is 10,000 kilometers, which is 109 times that of the earth. The volume of the Sun is 14.1 billion cubic kilometers, which is 1.3 million times that of the Earth.

The mass of the Sun is nearly 200 billion trillion tons, 330,000 times that of the Earth, and it concentrates the mass of the solar system.

Hello dear, according to current astronomical observations and research, we only know one solar system, that is, the solar system in which the earth is located. The solar system is a macroscopic system of celestial bodies composed of a stellar stellar cluster consisting of the Sun and its orbiting eight planets, dozens of moons, hundreds of millions of asteroids, and comets. While many other stars and planets have been discovered in the universe, no other well-defined celestial system like the solar system has yet been discovered.

Thus, it can be said that within the known range of astronomy, there is only one solar system in the universe.
