In the solar system, the sun is the center, but the solar system is only a galaxy in the universe.
-
No, the Sun is only the center of the Solar System, and the Solar System is at the outer edge of the Milky Way, and the Milky Way in which we live is not in the center of the entire universe.
-
Yes, the Sun is the center of the Solar System, and the Earth and the other seven planets revolve around the Sun.
-
The Earth we are on is a planet in the solar system.
The Earth where we are located is a planet in the solar system and one of the eight planets in the solar system, and the Earth, Venus, Mercury, and Mars are all rocky planets. Located in the best position in the solar system, the earth has abundant sunlight, abundant water resources and an oxygenated atmosphere, which is the cradle of life and the home of mankind.
The Earth is in the solar system, belonging to a celestial body in the solar system, and its mass and volume rank 6th among all the celestial bodies in the solar system, and the Sun, Jupiter, Saturn, Uranus and Neptune are larger than it.
The formation of the Earth
To put it simply, the formation of the Earth began with the contraction of the solar nebula, and the interstellar dust material (mainly ice and rocky, about millimeters in diameter) that was originally present in the nebula gas acted as a condensation nucleus, which slowly absorbed the particles scattered around it.
With the passage of time, the mass gradually increases, at this time it is called "star", and then the accretion process is more intense, the stars will collide and fuse, and finally form a protoplanet, and then further evolve into a planet, continuous accretion, continuous collision and fusion, and the earth is formed in this way.

Earth is one of the eight planets in the solar system, the third in order of being from the sun, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, 100 million kilometers away from the sun.
The Earth rotates from west to east while revolving around the Sun. Now 4.046 billion years old, it has a natural satellite, the Moon, and the two form a celestial system, the Earth-Moon System. It originated from the primordial solar nebula 4.6 billion years ago.
The Earth's equatorial radius is kilometers, the polar radius is kilometers, the average radius is about 6371 kilometers, and the equatorial circumference is about 40076 kilometers. The Earth's surface area is 100 million square kilometers, of which 71% is oceans and 29% is land.
The Earth's interior has the Earth's core, mantle, and crustal structure, and the Earth's exterior has the hydrosphere, atmosphere, and magnetic field. The Earth is the only celestial body in the universe known to have life, and is home to millions of creatures, including humans.

The relationship between the Sun, the Moon, and the Earth is:
All three are stars of the solar system and belong to the same solar system.
The Earth revolves around the Sun.
The Moon revolves around the Earth, and the two form the Earth-Moon system, and both revolve around the Sun at the same time.
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.
Earth is one of the eight planets in the solar system, the third planet in order from near to far, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, 100 million kilometers away from the sun.
The Moon, popularly known as the Moon, is the Earth's only natural satellite and the fifth largest in the solar system.

Question 1: Is the sun the center of the universe 500 years ago, a Pole named Copernicus said that the sun is the center of the universe. Because of the propaganda of this "heliocentric theory", Galileo was found guilty and Bruno was burned to death.
Because the Holy See says that the earth is the center of the universe.
200 years ago, a German (or British, so to speak) named Herschel said that the sun is not the center of the universe, and he was right. Until the beginning of the last century, people knew that the Sun was just an ordinary small star among the hundreds of billions of stars in the Milky Way, far from the center of the Milky Way. What the Sun does is carry all the large and small celestial bodies of the solar system (including the Earth) around the center of the Milky Way diligently.
And the Milky Way is only one of the hundreds of billions of galaxies in the universe.
Do you feel that the sun is the center of the universe?

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.
