BecauseSiriusMan is the highest dimension of the Andromeda Galaxy, the "Creator".Milky WayWhen they first came to the Milky Way, the whole galaxy was still in the embryonic stage, and the life form was relatively primitive, so the Hawkman created a series of "cathode" life, and the lion man created a series of "anode" life, and then let it develop freely, so as to be a "race" or "game".
Why did the "Creator" do this, you may ask? In fact, when human beings are promoted to a higher dimension, they will naturally understand that the higher the dimension, the more boring it is, and the more they know, the more boring it is, and there are only three and four dimensions.
This dimension with a physical experience is the most "fun", especially 3D, which is not as simple as 2D, and lacks change and information.
It is not like the four-dimensional space is too closely related, although the amount of information is large but tends to be integral, so only the existence and interaction of the three-dimensional "individual" is the most meaningful, it is precisely because the "creator" itself also participates in this "game", so some people in this group stay in the three or four dimensions of the galaxy and become Siriusians.
The Milky Way is different in light and dark in the sky, wide and narrow. The narrowest is only 4° 5°, and the widest is about 30°. However, the individual stars that the naked eye can see everywhere in the sky are all part of the Milky Way.
The light from this banded arc originates from the accumulation of light from stars and other celestial bodies on the plane of the Milky Way, which cannot be resolved by the naked eye.
For the Northern Hemisphere, the Milky Way is an important symbol of the summer starry sky, as well as 3 bright stars, namely Vega and Cowherd on both sides of the Milky Way.
and the "Summer Triangle" formed by the Tianjin Four in the Milky Way.
The Milky Way in summer is made up of Scorpio.
The east side stretches to the north, across the sky, and is majestic and magnificent. But it can only be enjoyed in the wild (above the ultimate visible magnitude) without light interference.
The Milky Way in winter is bleak (in the constellation Orion.
with Canis Major), but in the sky can be seen bright Orion, as well as by Sirius, Betelgeuse.
Fourth, the bright "winter triangle" composed of the three rivers of the South River.

Sirius is within the Milky Way, and it is only light-years away from the Sun, while the radius of the Milky Way is 50,000 light-years. So, Sirius is not only in the Milky Way, but also one of the closest stars to the Sun.

1. Sirius.
Within the Milky Way, it is only light-years away from the Sun, while the Milky Way has a radius of 50,000 light-years. So, Sirius is not only in the Milky Way, but also one of the closest stars to the Sun.
2. A star system like Sirius, which consists of two stars, is called a binary star system.
Very common in the universe. It has been observed that at least in the Milky Way, more than 70% of the stars exist in the form of binary stars. There are not many individual stars like the Sun, no more than a quarter.
3. The stars we see with the naked eye, except for the sun, the moon and the planets of metal, wood, water, fire and earth, are all stars, and they are all stars in the Milky Way. The planets themselves do not emit light, and even though there are more planets than stars in the Milky Way, we cannot see them without stars illuminating the planets. Planets are too massive compared to stars to shine on their own.
And celestial bodies like the Sun and Sirius, because they are much more massive than planets, can trigger nuclear fusion reactions inside.
That's why it's so bright, that's why it's called a star.
4. The Milky Way is a very large star aggregation system, with a diameter of 100,000 light years, including stars, nebulae and interstellar dust. Together, they orbit non-stop around the center of the Milky Way, just as the Earth orbits around the Sun. And the Sun is just a very ordinary star in the Milky Way.
5. Stars are huge gaseous planets in the universe that rely on thermonuclear fusion reactions to emit light and heat themselves. Both the Sun and Sirius are stars.
6. The exact number of stars in the Milky Way is not yet known. Astronomers estimate that there are no less than 200 billion.
7. Sirius is larger than the Sun. The mass is about twice that of the sun (different information is not the same).
8. The sun is an inconspicuous little brother in the Milky Way, with a small mass and a small stature, so small stars such as the sun are called yellow dwarfs.
9. There is no information on TRES-4, so it is not clear.
The Milky Way and nearly 40 other galaxies that are not very far apart form a cluster of galaxies, all of which have a more or less mutual gravitational pull. Of these, the Milky Way and the Andromeda Galaxy are the two largest and closest galaxies, and the distance between them is only 2.5 million light-years Reference.
Give so many points, I'll also join in the fun. The landlord's question is of little practical significance, referring to the upstairs Du Kang and nostalgia. Bigger than China is the world, bigger than the world is the Earth-Moon system, larger than the Earth-Moon System is the Solar System, larger than the Solar System is the Milky Way, larger than the Milky Way is the total galaxy, and there is no definition of a universe larger than the total galaxy.
The galactic center is the intersection of the Milky Way's axis of rotation and the galactic plane, the center of the galactic core, and the center of the Milky Way. The Silver Heart is located in the direction of Sagittarius. This region is mainly made up of a large number of stars. >>>More
Yes around the silver core.
The Sun also has a speed of revolution relative to the center of the Milky Way. >>>More
Looking at the Milky Way from outside the Milky Way, the Milky Way is just a very ordinary galaxy, no different from other galaxies, and there are countless galaxies like the Milky Way in the universe.
