Extended data:

Take the earth in the solar system as an example. The structure of the astrolabe is usually, from the outside to the inside, as follows: the first celestial palace, the longitude of the ecliptic, the second celestial palace, the astral region, and the geocentric region. Among them, the congenital and the second celestial palace are marked with twelve kinds of astral symbols that dominate the zodiac.

According to different systems, the axis passing through the center of the earth on the astrolabe represents different meanings, but in most systems, the horizontal axis represents the horizon (terminal line), and the left side is called rising and the right side is called falling. The axis with a difference of 23 26' from the horizontal axis represents the You Mao line, with the east point on the left and the west point on the right.
