Solar system. The center of the solar system is not the center of the sun, the center of the solar system is the center of mass of the solar system.
That is, the center of all mass solar system celestial bodies revolves around it, and the sun does not have 100% mass in the solar system, so the center of mass will not be the center of the sun. The center of mass is the true center of a galaxy, and even the sun is moving around this center of mass, but most of the time the center of mass is inside the sun, so the movement of the sun is difficult to detect, why most of the time? Actually, it's because the center of mass changes.
The center of mass is not a fixed point, and in rare cases, the center of mass will be outside the Sun, which is the case of the Eight Planets.
On the same side of the Sun, let the mass of the entire solar system be biased to one side because of centrifugal force.
, the center of mass will be farthest from the sun. But this is rare, so in most cases, the center of mass is inside the sun, which is actually the equilibrium point of the solar system. The center of mass is the true center around which all the celestial bodies of the solar system revolve, but the position of the sun is still difficult to shake.
The existence of the center of mass is a major discovery of scientists studying galaxies, and this discovery has made the heliocentric theory wrong to a certain extent, which holds that what is stationary on the sun, in fact, the sun also moves around the center of mass. Moreover, the sun is not stationary, it is scientists observing the Milky Way.
The solar system revolves around the Milky Way under the leadership of the sun, and the center of mass of the Milky Way is the galactic black hole, the galactic astrolabe.
The distribution of celestial bodies is relatively uniform, so there is basically no shift in the center of mass.

The center of the solar system is the Sun.
The solar system is oneCentered on the sun,and a celestial system that is maintained by its gravitational pull.
The solar system includes the sun, planets and their moons, dwarf planets, asteroids, comets, and interplanetary matter. They all exist around the sun, and without the sun, the solar system would not exist.
-
The sun is the central body of the solar system and occupies the overall mass of the solar system.
The eight planets in the solar system, asteroids, meteors, comets, outer Neptune objects, and interstellar dust all revolve around the Sun, which revolves around the center of the Milky Way.
The Sun is an ordinary star in the Milky Way, with an average distance of 149.6 million kilometers from the Earth, a diameter of 1.39 million kilometers, an average density of centimeters of cubic stoves, a mass of grams, a surface temperature of about 6,000 Ke, and a central temperature of 15 million Kelv. From the inside to the outside, they are the anti-empty hunger area of the solar nucleus, the solar troposphere, and the solar atmosphere. [46] Thermonuclear reactions are constantly taking place in its central region, and the energy produced is radiated into space.

The sun is the center of the solar system, the earth is a planet in the solar system and the moon is a natural satellite of the earth.
-
Yes, the Sun is the central body of the Solar System, the only star in the Solar System, and the closest star to Earth.
-
The sun isSolar system. of the central celestial body.
The reason why the sun is the center of the solar system is not because the sun is the only star in the solar system, nor because of how huge the mass of the sun is, not because of the light and heat it emits, the reason why the sun is the center of the solar system is because in the solar system, all the celestial bodies represented by the planets are orbiting the sun in an orderly manner.
All celestial bodies controlled by the gravitational pull of the Sun
The first is the large family of planets very close to the Sun, as well as our artificial satellites, and some Sun-grazing comets.
Asteroids and more. Except for some artificial satellites, comets, asteroids, etc., most other celestial bodies orbit the Sun in the same plane (ecliptic). It's just to Pluto.
In addition, some celestial bodies known as the ecliptic discrete orbit away from this plane.
Further beyond is a hypothetical theoretical comet** known as the Oort Cloud.
Its orbit is spherical and encircles the entire solar system in its outermost layer.

The exact coordinates of the Earth in the universe areLaniakea Supercluster - Virgo Cluster - Home Group - Milky Way - Orion Arm - Gould Belt - Local Bubble - Local Interstellar Cloud - Oort Cloud - Third Planet of the Solar System - Earth.
There are countless celestial bodies in the universe, which can be classified into stars, planets, moons, meteors, comets, nebulae, and so on. Stars are so massive that they can emit light and can be seen with the naked eye, and above 99 are stars.
From Earth, the relative positions of stars seem to be fixed, but in reality, all stars are in constant motion. Planets do not emit light on their own, have much less mass than stars, and orbit stars. The Earth is one of the planets that orbit the Sun.
Earth is a planet in the Milky Way in the Laniakea Supercluster.
Earth plane coordinates.
Every year, if you stand on the earth and look up at the starry sky, you will also find that the astronomical phenomenon is somewhere in the sky. That's the plane coordinates of the earth. The direction in which a star is located is usually from the perspective of due north to east.
The earth is at the core of the sphere, composed of a graticule map, and the observed objects are located on a curved surface, so the observed objects have "geographical coordinates", and the latitude and longitude in astronomy is called "right ascension", which is not indicated by myopia, but is a 24-hour clock, with a rotation of 24 hours.

No. If you go to the solar system, the sun is the center. Out of the solar system, the universe is an infinite space, and there is no center.

In the vast space, stars are not willing to be lonely, they like to be in piles, or pairs, or groups of three or five, and some even thousands, or even hundreds of thousands, millions of them gather together to form globular clusters, some of which form the skeleton of the Milky Way. Their center is the center of the Milky Way. According to the model of the Milky Way described by the British astronomer Herschel, the Milky Way is a flat, space-limited star system, like a piece of baked cake that has been bitten unneatly by a child, and the solar system where the Earth is located is located in the center of the baked cake.
By this reasoning, the Sun should be at the center of the Milky Way, and the clusters of stars in the Milky Way should be scattered around the Solar System. According to Herschel's theory, globular clusters should be visible everywhere in the sky from Earth, but this is not the case. One-third of the globular clusters are clustered around the Big Dipper, and the remaining two-thirds are mostly located in the half-celestial sphere centered on the constellation Sagittarius.
Original address: It is 30,000 light-years away from the center of the Milky Way.

The center of the Milky Way is a very strong radio source, and this intense radio source center is very small, and at the same time, it is also very likely that a huge black hole will be created at the center of the Milky Way.
-
The center of the Milky Way is, of course, the nuclear sphere, which is the most central part of the Milky Way and one of the most beautiful places in the Milky Way.

I feel that the center of the Milky Way is the universe, so I think the Milky Way is very mysterious.
The solar system is a system of celestial bodies made up of the Sun and the celestial bodies that orbit it under its gravitational pull. It includes the Sun, the eight planets and their moons, dwarf planets, asteroids, comets, meteoroids, and interstellar matter. The celestial bodies in the solar system are mainly composed of gases such as hydrogen, helium, and neon, ice (water, ammonia, methane), and rocks containing elements such as iron, silicon, and magnesium. >>>More
At present, the Nebula theory is the dominant view. For more information, please refer to the encyclopedia.
Nine planets, including the Earth, form a planetary system that revolves around the Sun. The closest planet to the Sun is Mercury, followed by Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. With the exception of Mercury and Venus, all planets have moons. >>>More
