What generation of stars is the Sun? There are several major stars in the solar system

If our Sun is only a first-generation star, meaning that it is almost entirely made of hydrogen, then it is questionable whether planets can form around it. Because the planets at this time did not have higher elements as raw materials, if they could form small clumps of hydrogen, which were difficult to condense and would be dispersed by the solar wind, it was impossible for the first generation of stars to form a planetary system at the same time. Our current Sun is a second- or even third-generation star, so it has a rich elemental content.

The planets of our solar system, on the other hand, are entirely composed of the remnants of the sun (star) of the previous generation or generations. The old and dead stars of the previous generation were broken and scattered in the universe, forming particles of iron and other elements, and the "supernovae" of the previous generation formed elements heavier than iron and radioactive elements. They coalesce to form the planets of our solar system.

Our planet has a dense iron core, our planet is rich in mineral deposits (composed of various elements), and our planet has its own energy source, mainly energy supplied by the metamorphosis of natural radioactive elements. All this shows that we are enjoying the legacy of the previous generation of the sun. It was the creation of planetary systems on the wreckage of the previous generation of suns, including our Earth.

Most of our energy depends on the sun today, but the nuclear energy we developed on Earth is the energy accumulated during the supernova explosion of the previous generation. Without these many elements, without the necessary energy, life would not have been possible.

The sun is 5 billion years old.

It should be the third generation.

There may have been another star system in the previous position of the solar system.

The solar system revolves around the Milky Way.

The sun is the second generation of stars, and the sun and his father blew it up in 124 A.D. because he played the game too fiercely, and the computer blew it up.

In short, not the first generation.

It is likely that the first generation of stars, unlike the various stars we see now, were massive and almost all of them were hydrogen and helium.

Generations of supernovae inject heavy elements into the nebula, and shock waves cause new stars to be born in the nebula, but the proportion of heavy elements in the new stars continues to increase.

Not the first generation of stars.

The first generation consists entirely of H (hydrogen).

And the sun is not all made up of h (hydrogen).

So not the first generation of stars.

Does the landlord want to ask how many stars the sun has produced since the birth of the universe?

No can not say how many generations.

There is 1 star in the solar system

There are 8 planets in the solar system [Mercury.

Venus, Earth, Mars, Jupiter.

Saturn, Uranus, Neptune].

In addition, there are 5 dwarf planets [Ceres, Pluto, Eris, Ornith, Haumea] and some candidate dwarf planets, which are not asked by the landlord, so I will not introduce them here.

In terms of stars and planets, the Sun belongs to the category of stars because the gravitational pull inside the Sun is sufficient to condense hydrogen matter, and the mass is high enough to ignite the hydrogen matter to convert energy and make itself shine. Planets can't live up to that. But in the vast galaxy, the Sun is only a medium-sized star.

The Sun is a star.

In terms of the definition of a star, the Sun is certainly able to meet the definition of a star as a planet. The gravitational pull inside the Sun is strong enough to condense the hydrogen material, and the mass is so massive that it ignites the hydrogen material to convert the energy and make itself shine, and from this point alone, the Sun can be used as a star.

In the solar system, the eight planets are all under the gravitational pull of the sun, following the sun to make an orbit. The Sun is the only star in the solar system, and the other stars are either planets or moons, or other dwarf planets. Their volume and mass are not comparable to that of the sun.

The hydrogen contained in the sun is constantly undergoing thermonuclear reactions, so that the sun can always emit light and heat, and its surface temperature is almost 6000, not to mention the internal temperature will be even higher. In the solar system, the Sun is already considered a large star, but in the Milky Way, the Sun is just an ordinary medium star.

Everyone should know that the Sun is definitely not the largest star in the universe. The Sun is the closest star to us. The universe is so big that it's hard to say which one is the biggest.

In 2010, British scientists discovered a supermassive star with a mass of 300 suns, 10 million times brighter than the sun, and it is located in the center of the tarantula nebula.

The size of the Sun is almost insignificant compared to the red giant. However, red giants are the last form of star evolution, and their size is very large. But the mass of the red giant is basically the same as that of the Sun, and the density of the red giant is very small.

There are many stars in the universe, and you never know if there are bigger stars.

The Sun is only the largest star in the Solar System, but there are many stars larger than the Solar System in the universe alone.

The sun is an ideal sphere of hot plasma intertwined with a magnetic field. The diameter of the sun is about 10,000 kilometers, which is equivalent to 109 times the diameter of the earth; It is about 1.3 million times the size of the Earth; A star in the constellation Cetus is 460 times the diameter of the Sun, and a star in the constellation Orion varies between 700 and 1,000 Suns in diameter. But because the sun is closest to the earth, it looks very large and bright.

If you look at the Sun from another star, the Sun is just a point of light.

The Sun is a star.

The Sun is just a very ordinary star in the universe, but it is the central object of the solar system. In the solar system, eight planets, including our Earth, some dwarf planets, comets and countless other small bodies of the solar system orbit the sun under the strong gravitational pull of the sun.

The gravitational pull inside the sun condenses the hydrogen mass, and the mass reaches the point where it ignites the hydrogen matter to convert the energy and make itself shine, almost an ideal sphere intertwined with a hot plasma and a magnetic field. There are 50 closest star systems at a distance of 17 light-years from Earth, and the closest star to the Sun is a red dwarf called Proxima Centauri, about light-years.

Introduction to Planets.

Planets, usually referring to celestial bodies that do not emit light on their own and orbit a star, get their name from the fact that their positions are not fixed in the sky, as if they were walking, and their orbit is often in the same direction as the rotation of the star they orbit. Generally speaking, planets need to have a certain mass, and the mass of the planet must be large enough to be as similar to spherical as it is, and it cannot undergo nuclear fusion reactions like stars.

Historically, planets got their names from the fact that their positions were not fixed in the sky, as if they were walking in the stars. The five planets visible in the solar system, namely Mercury, Venus, Mars, Jupiter and Saturn, have been discovered by humans as early as prehistory.

One, the sun.

The Milky Way is a bar-spinning galaxy about 100,000 light-years in diameter and includes between 100 billion and 400 billion stars. The Sun is a typical star of the Milky Way, located on the branch cantilever Orion Arm, 10,000 light-years away from the center of the Milky Way, and the solar system rotates around the center of the Milky Way at a speed of about 240 s, one revolution in 100 million years.

The eight planets in the solar system all orbit in a near-circular orbit in about the same plane, orbiting the sun in the same direction. With the exception of Venus, the other planets have the same direction of rotation and revolution. Most comets orbit in the same direction around the Sun, most of them have elliptical orbits, and generally have a long orbital period.
