This phenomenon was in line with Copernicus's theory of the sun's center. Copernicus believed that the sun was at the center of the universe, and the earth was an ordinary planet that revolved around the sun. On one hand, it rotated around the earth's axis, and on the other hand, it revolved around the sun in its own orbit, while the moon revolved around the earth. This theory overthrew the previous geocentric theory and was a major revolution in astronomy, causing a major change in the human view of the universe.
The earth goes around the sun;The earth revolutions around the sun.
I recommend Planet Escape. This book was a sci-fi doomsday crisis novel written by Love Fighting the Landlord. Earth deviated from its orbit and flew out of the solar system. All kinds of disasters erupted. After humans entered the era of black technology evolution, they built spaceships to escape. The protagonist Xiang Gan was reborn before the disaster and wanted to lead Earth to roam the sea of stars. This book had a big imagination. The setting of escaping with Earth was very interesting. The beginning was well written. Although the end was a little broken and the ending was rushed, the flaws did not obscure the merits. There was a lot of scientific hypothesis knowledge in it, and the author could explain the principles of science fiction in common language. It was easier to understand and more interesting than " The Three-Body Problem." The book also talked about human migration in space, such as the O'Neill cylinder and the Bernal sphere. On the whole, the combination of apocalypse and space elements was very immersive. The writing style, logic, and coolness were all okay. It was a science fiction novel worth reading. You can also take a look at " Digging the Earth ", an urban supernatural novel written by Fu Bao. The main character, Zhou Yun, explored the Earth, searched for lost treasures, and solved the unsolved mysteries of the Earth, such as the secrets behind the underwater pyramid and the crystal skull. The style was more relaxed and refreshing, a little like Golden Pupils, but the author was not very reliable. His previous works were often incomplete, and this book had a lot of repetitive passages. However, if there was a book shortage, he could use it to kill time. There was also " Cataclysm of the Earth ", a sci-fi futuristic novel written by Shi Mian. There was a mysterious void corridor in the universe. The supernova explosion did not destroy Earth but allowed life to evolve again. The story of the youth rising up in the universe after growing up on Earth. Doomsday novel lovers could pay attention to it. Zombie: Rejecting Ninth Uncle at the Beginning was not bad either. It was a novel written by the great monk of Pingkang Lane, a suspense novel in a wonderful world. The male protagonist traveled through the zombie world because the system gave up on taking Uncle Nine as his master and chose his beautiful junior sister. It was a story about the collision of various elements between Chinese martial arts and the zombie world. The world setting was grand. Finally, there was One Piece Duplication, a light novel by September Sakura. The story had elements such as dimensional chat groups. It was exciting to see if the invincible Moen could change other worlds. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
"Earth Online" was an original science fiction novel by Mo Chenhuan. It started on November 16, 2017 in Jinjiang Literature City and ended on November 10, 2018. The full text was 1341652 words. The book version was published by Tianjin People's Press in March 2020. The story was set as a black phantom tower suddenly appearing on Earth. The ordinary librarian Tang Mo obtained a special ability in the disaster and met Fu Wenduo, the captain of Special Team A of the Southwest China Military Region. They joined hands to challenge many game instances such as Kill Bill, Cinderella's Food Chain Game, Blizzard Villa, etc., constantly unlocking new levels and abilities. They gradually discovered that the purpose of the black tower's existence was to promote human evolution rather than destroy human beings. In the end, the black tower went offline and humans came back online to start a new era of civilization. Tang Mo and Fu Wenduo also gained love. This novel had keywords such as indulgence, science fiction, cool literature, leveling up, and relaxation. It had the brain-burning characteristics of the infinite novels, but the plot was not bad. It was divided into reality and the game world. Although there were few emotional lines, it was very sweet. The text was humorous and the overall style was relaxed. It was more friendly to readers who had just come into contact with the infinite genre. In March 2021, the novel was prepared to be filmed as a science fiction drama.

This described the phenomenon of the earth revolving around the sun. The Earth revolved around the Sun in a fixed orbit. Its orbit was an oval orbit with an average radius of about 150 million kilometers. The center of the revolution was the common center of mass between the Earth and the Sun. The direction of the revolution was from west to east, and the revolution period was one year. Because the orbit was oval, the distance between the Earth and the Sun changed during the revolution. The closest position to the Sun (perihelion) was generally in early January after the winter solstice, and the farthest position from the Sun (aphelion) was generally in early July after the summer solstice. The plane on which the Earth revolved was called the ecliptic plane. When the Earth revolved, its axis tilted and its direction did not change, causing the amount of sunlight and heat obtained at different times and places to be different, resulting in the change of the four seasons. According to the amount of sunlight and heat obtained by different places, the Earth's surface was divided into five zones: the tropical zone, the northern temperature zone, the southern temperature zone, the northern frigid zone, and the southern frigid zone. During the Earth's revolution, there were two cycles, the tropical year and the stellar year. The difference of one year between the two was called precession.
It takes 365.25 days for the Earth to circle the sun, which is the length of Earth's stellar year. The Earth's revolution period was the time it took for the Earth to make one revolution around the sun, which was also the standard of the Earth's year. The Earth follows an oval orbit around the Sun at a speed of about 108,000 km/h. The Earth's axis of rotation has an inclination with respect to the direction of its orbit, which causes the day and night changes and seasonal changes at all latitudes of the Earth. The Earth actually moves about 365 days and 6 hours a year, so we have leap years to make up for the difference between the Earth's revolution and the calendar.
The time it takes for the Earth to orbit the Sun is a stellar year, which is 365 days, 6 hours, 9 minutes and 10 seconds, or 365.2564 days. The Earth's revolution period could also be measured by the annual apparent motion of the sun. Due to the different reference points selected, the length of the " year " was also different. The commonly used units of the cycle were the tropical year and the closest year.
The earth would revolve around the sun. The sun was a star located at the center of the solar system. Its powerful gravitational force caused all the planets, including Earth, and other celestial bodies in the solar system to revolve around it.
The sun was the central star of the solar system, occupying 99.86% of the solar system's mass. The eight planets in the solar system (including Earth) and many asteroids revolved around the sun. Earth was one of the eight planets in the solar system. It was ranked third in terms of distance from the sun. It was a terrestrial planet. The moon was the only natural satellite of the earth. It had a large mass and revolved around the earth. In addition, due to the relative position changes of the sun, the earth, and the moon, there would be solar and lunar eclipses. Solar eclipses were caused by the moon moving between the sun and the earth, blocking the sun's rays. At this time, the position relationship was the sun, the moon, and the earth. Lunar eclipses were caused by the moon moving to the shadow position of the earth. The sun's rays were partially blocked by the earth, and the position relationship was the sun, the earth, and the moon. In the three-body system, when the mass of one celestial body was negligible compared to the other two, the remaining two celestial bodies would move in an oval motion around the center of mass according to Kepler's law. The small celestial body would move in the joint gravitational field of the two celestial bodies, but the trajectory of the small celestial body was complicated. Even if the initial conditions were given, it would enter a chaotic state over time. Although the Moon was locked by the Earth's tides, due to the difference in mass between the Earth and the Moon, it would not pull the distance between the Earth and the Moon until the Earth was also locked by the Moon's tides. Now, the Earth and the Moon faced each other on the same side for billions of years, forming a dual planetary system that revolved around the Sun and each other.
The sun, the earth, and the moon had various positions: 1. When it is a new moon, the sun, the earth and the moon form a straight line, and the moon is in the middle. 2. When the first quarter moon, the sun, the earth and the moon form a right angle. 3. When the moon is full, the sun, the earth, and the moon form a straight line, with the earth in the middle. 4. At the last quarter of the moon, the sun, the earth and the moon form a right angle. A simple description of the location relationship was as follows: - New Moon: The sun's rays shine towards the Earth. The moon is located between the sun and the Earth. At this time, the moon is invisible from Earth (because the dark side of the moon faces the Earth). - First Quarter Moon: The Earth, the Moon, and the Sun form a right-angled triangle. Looking at the Moon from Earth, the west (right) side of the Moon is bright. The first quarter moon appears in the first half of the night, in the western sky. - Full Moon: The Earth was located between the Sun and the Moon. The Sun's rays shot toward the Earth, and the Earth reflected the rays toward the Moon. At this time, the Moon was a complete circle from Earth. The full moon could be seen from evening to dawn, appearing in the entire sky from east to west. - Last quarter moon: Earth, the moon, and the sun form a right triangle (opposite to the first quarter moon). When looking at the moon from Earth, the east (left) side of the moon is bright. The last quarter moon appears in the second half of the night, in the eastern sky. The novel New Moon is equally exciting. Everyone is welcome to click and read it!
