What is the biggest star in the entire sky?

Undoubtedly, the brightest object in the firmament is the Sun, which stands as tall as the Moon in terms of perspective. Let's take these two with you at the beginning, otherwise someone may criticize me for not thinking it through.

After deducting these two special celestial bodies, the brightest star in the whole day (that is, the largest in appearance) is Venus, which can reach its brightest in early December, and even shine shadows in places with excellent conditions.

Jupiter is usually the object with the largest viewing angle with a telescope, and the angle of view before and after opposition (closest to Earth) is about 41 arc seconds, and many details can be seen in the telescope.

If you don't count the celestial bodies in the solar system, the brightest is Sirius, and the largest angle is Aldebaran. The brightness of the former is equal, and the angle of view of the latter is arc seconds, so for the two planets mentioned earlier, the difference is still very large, right?

If asked about its own nature, the largest star found so far is VY Canis Major, and the most massive star is R136A1. There must be objects in the universe that are larger in volume and mass than them, but these two stars are very close to the theoretical upper limit, and even if new discoveries are made in the future, it is still correct to add the word "one" to them.

People are talking about the starry sky, and it must be Sirius.

I forgot that there used to be ...... on WeiboSearch for it and you'll find the answer!

There is no biggest star in the world.

Stars are divided into stars, planets, moons, comets, meteors. Stellar: To put it simply, it's glowing, it's a big thief, it's always moving, it's just too far away from the earth to be seen.

Planets: do not emit light, orbit stars. Satellite:

Stars that revolve around the planets cannot emit light, and the moon is the representative. Comet: Composed of ice and cosmic dust, it is held by a star while pulling out a tail.

Meteor: An aimless flying star or debris in the universe. Comets are, of course, a type of star.

Larger than the Sun is Sirius, North River Three, and the boss is the Shield Uy, which is 21 billion Suns in size.

The constellation Uy is equivalent to 5 billion suns.

Everyone knows that the largest planet in the solar system is Jupiter, but there may be larger ones outside the solar system, which cannot be estimated at the moment.

U.S. astronomers have discovered the largest star in the universe with a circumference 1,500 times that of the sun, and according to foreign news reports, the three red and bright stars recently discovered by American astronomers have been confirmed as the largest stars observed so far. Astronomers' research notes that the three stars discovered are more than 1 billion kilometers in diameter and 1,500 times the circumference of the Sun. If these three stars take the Sun's place, they will be hot enough to "engulf" the Earth; Their outer space can even extend between the orbits of Jupiter and Saturn.

Betelgeuse, the widely known super-large star and the largest star of the Orion Nebula, pales in comparison to these three large stars. They are also slightly larger than the Pomegranate Star of the Herschel Cloud, the largest previously known star.

Using computer models, astronomers found that the temperature of the three red giants was about 5,600 degrees Fahrenheit (3,100 degrees Celsius), and that the hottest known star, the Sun, was over 90,000 degrees Fahrenheit (50,000 degrees Celsius). At the same time, researchers are working to calculate the volume of the three stars. Astronomer Marcy revealed that the three red giants are all nearing the end of their life cycles, with extremely low temperatures, extremely bright luminosity, and a large volume.

In addition, scientists now know the distance between the three red giants and the Earth, as well as the brightness of the stars.

Most of the stars you can see are stars, but there are also many red giants that are close to old age, and occasionally the brightest one that can be seen in the morning is "Venus" (the morning star), and the bright planet that can be seen even if it is not visible to other planets every night a while ago (as long as it is not a big cloudy day) is Jupiter, which was probably the same when Mars was at opposition a few years ago.

If you're lucky, you'll be able to see a supernova (the big ** after the end of the star), which is particularly bright.

If you are more romantic, you will occasionally see meteors (usually the rings from Jupiter, which is the appearance of some lost "children" in the asteroid belt who have broken away from the organization and come to the earth, and enter the earth's atmosphere by rubbing against the atmosphere).

Stars, planets, moons, comets.

When you're in a good mood, the sky is full of stars, and when you're in a bad mood, even if the sky is full of stars, it's dark, and there are no stars

There are no stars, only planets. -
