Is Jupiter too old?

So the gravity of this star on earth is the first among the stars. Dr Allen Bos of NASA admitted that Jupiter's great gravity can protect the earth from comets and asteroids. Jupiter is the most striking planet in the solar system. Its brightness is second only to Venus. In ancient China, it was called the "year-old star", which was used to date the years because it was known that its period of revolution was close to 12. However, after Chinese astronomers discovered that Jupiter's orbit was actually not 12, they imagined a star with the same orbit, but in the opposite way. This imaginary star is called Tai Sui. Heavenly stems and earthly branches has also evolved with the traditional operation. Every year, when Jupiter reaches a certain position on the earth, it will strengthen the gravity of this position. Tai sui changes with the years. Tai sui is in the dry palace this year, northwest-west. The ancients had the concept of twelve days, that is, twelve equal parts of a week near the ecliptic, with twelve branches, such as Zi Ugly Yin Mao, from east to west, arranged in the opposite direction and order. The year-old star runs from west to east, just contrary to the direction and order of the twelve dates we are familiar with, so it is not convenient to apply the year-old star chronology in real life. Therefore, ancient astronomical astrologers invented a false old star named Tai Sui, and made it "run counter to the true old star" to make it consistent with the direction of 12 years old, and used it to calculate the year.
