Will the sun get bigger, what is bigger than the sun

By the time the sun was dying, it had changed so much, it seemed like a red giant, and I forgot about it.

The size of the Sun is equivalent to 130 Earths.

It is a star at the center of the solar system. The diameter of the Sun is very large, about 1.39 million kilometers, which is 109 times the area of the Earth. In the solar system, the Sun is the first celestial body, accounting for 99% of the total mass of the solar system, but the Sun always revolves around the Milky Way.

The relationship of the Sun to the Earth and the Moon.

The Earth belongs to a star in the solar system and has been orbiting the sun for a year. Although the Moon is a satellite on Earth, it always revolves around the Earth, and it rotates for a month. The Sun is the center of the solar system, and the Earth belongs to the planets of the solar system.

The Moon is a satellite on Earth. When the Sun, Earth, and Moon line up, there will be a solar eclipse and a lunar eclipse. It's not very common, but when it happens, everyone can see it clearly.

As the Earth revolves around the Sun, it absorbs the Sun's light and heat.

While absorbing light and heat, the earth also gives birth to life on the earth. Therefore, the earth on which human beings depend cannot survive without light and heat. Without the sun, the earth would always be dark.

If there is no moon, then humans on Earth cannot rest day and night. Although the sun is like a big fireball, it is really very important to the earth.

Summary. The Sun is a star in our solar system, it is the closest star to us and the largest celestial body in our solar system. Therefore, there are no stars in the universe that are larger than the Sun.

However, there are many other celestial bodies in the universe that are larger than the Sun, such as planets, galaxies, and so on. For example, Jupiter is the largest planet in our solar system, about one-tenth the diameter of the Sun, but it has only one-thousandth the mass of the Sun. In addition, there are many galaxies in the universe, each of which is made up of millions to trillions of stars, some of which have stars much larger than the Sun.

In conclusion, although there are no stars larger than the Sun, there are many other celestial bodies in the universe that are larger than the Sun.

The Sun is a star in our solar system, it is the closest star to us and the largest celestial body in our solar system. Therefore, there are no stars in the universe that are larger than the Sun. However, there are many other celestial bodies in the universe that are larger than the Sun and more than the Sun, such as planets, galaxies, and so on.

For example, Jupiter is the largest planet in our solar system, about one-tenth the diameter of the Sun, but it has only one-thousandth the mass of the Sun. In addition, there are many galaxies in the universe, each of which is made up of millions to trillions of stars, some of which have stars much larger than the Sun. In conclusion, although there are no stars larger than the Sun, there are many other celestial bodies in the universe that are larger than the Sun.

Can you add, I don't quite understand it.

Sorry, mine may not be very clear, it confuses you a little. I mean Bi Jaen, and from what we have seen so far, the Sun is the largest star we know of, and no other star is bigger than the Sun. However, there are other celestial bodies in the universe that are more invisible, such as planets, star clusters, galaxies, etc., but they are not stars.

No, the largest star ever discovered is the star R136A1. The most massive and brightest star known today is R136A1. RMC 136A1 (often abbreviated as R136A1) is a Wolf-Laye star located at the center of R136, at the center of the Spider Nebula NGC 2070 cluster.

It is in the Large Magellanic Cloud about 50,000 parsecs (163,000 light-years) from Earth. Its mass and brightness are the highest of any known star, with a solar mass of 256-265 and a solar mass of 7.4 million-8.7 million solar luminosity, so R136A1 has a temperature of more than 49,000 (or 50,000 K) degrees Celsius, but is smaller than some stars, about twice the diameter of the Sun.

The sun is not the largest, it is the largest in the solar system at 99%. And there are countless stars that are bigger than the Sun, the largest objects in the solar system, no, it's the largest in the solar system, but there are many more in other systems.

The sun is definitely not. The universe is huge, and it's hard to say which one is the biggest. But which star is the largest, I can tell you.

That's the red giant max. This is a form of stellar evolution that is usually very large, and the Sun is nothing compared to the red giant. But the mass of the red giant is basically the same as that of the Sun, so the density of the red giant is very small.

Betelgeuse of Orion.

Fourth, the big horns of the constellation are red giants. When the Sun turns into a white dwarf, it will be billions of years away. By then, humanity had either perished, or technology had advanced enough to immigrate to other planets.

The size of the Sun is 1,300,000 Earth, and the diameter of the Sun is 10,000 kilometers.

The temperature of the sun is very high: the surface temperature is 6000 degrees Celsius; The core temperature is 15000000.

There are also bigger stars, not stars with the highest surface temperature of the Sun:

The mass of the star is more than 20 times more than that of the Sun, and the greater the mass, the higher the surface temperature, with the largest surface reaching 80,000 degrees Celsius.

The sun doesn't get bigger at sunset. It's just that after being refracted by the sunset and water vapor, people's feelings become bigger.

That's because of the different references, but the sun is as far away from us as it is at noon and in the evening.

The sun doesn't change, it's just that our perspective changes.

It's because of the problem of atmospheric refraction.

Anyone who has studied optics knows that light is refracted through different media.

The universe is almost vacuum, and refracted into the Earth's atmosphere.

At sunset, the sunlight enters the atmosphere at a relatively oblique angle, so the refractive angle is larger, so it looks like the sun is large.

Not just at sunset, but also at sunrise.

Two reasons: 1. Parallax:

Different times to observe the sun, the reference is different, causing parallax.

At sunset (rising), the reference objects for the human eye to observe the sun are some scenery on the ground, such as: trees, houses, mountains, fields, ......;

At noon, the reference object for the human eye to observe the sun is the sky.

The trees, the houses, the mountains, and the fields are much smaller than the sky.

2. Lens effect:

There is an atmosphere on the surface of the earth, and the atmosphere is spherical.

Observing the Sun at sunset and observing the Sun at noon is different from the atmosphere through which the line of sight passes. This is equivalent to an optical lens.
