Why are the years different, the month and the day the same, but the constellations different?

Is the date of the constellation different every year? Sun constellation = origin and query list: scientists use modern scientific methods to calculate the possible formation time of the top ten planets in the solar system so far! About/kloc-0.5 billion years ago, there were ten planets in the solar system: the sun, the earth, Jupiter, Mars, Saturn, Venus, Mercury, Neptune, Uranus, Pluto and the moon (the moon is just a planet on the earth = the moon goes around the earth once a day = it is generally called a week). After the formation of the solar system, every planet has its own cause and effect (natural law)! Fixed orbit. That is to say, the planets in the solar system rotate and revolve periodically year after year in their own specific time. The sun is the main star among the ten planets in the solar system, and it is the only star that constantly produces heat and light, so scientists call it a star. The sun is the main star of the ten planets in the solar system. The other nine planets all revolve around the sun in their respective orbits (commonly known as revolutions). During this period, the distance from each planet to the sun is also different (because the distance from each planet to the sun is different). In period of revolution, a planet in the solar system, not every planet always moves forward in its orbit, but there are some planets in the middle, sometimes forward and sometimes backward. However, the cycle time and pattern of each planet's revolution around the sun are fixed. We know from the astronomical ephemeris that the planets in the solar system revolve around each year as follows: the sun is the main star of the solar system, so it only rotates once a year, and there is no revolution. Earth: it orbits the sun once a year, and the orbit around the sun is commonly known as the ecliptic. Jupiter: It orbits the sun once every 65,438+02 years.
