How is the 12 constellation formed?

1922, the General Assembly of the International Astronomical Union decided to divide the sky into 88 constellations. In other words, there are 88 constellations in the sky that divide the whole celestial sphere. 1928, the international astronomical union officially announced the names of 88 constellations. These 88 constellations are divided into three celestial regions, 29 in the northern hemisphere and 47 in the southern hemisphere, near the ecliptic 12. Constellation 12 refers to the constellation 12 on the ecliptic. The ecliptic is the path of the sun through the sky during the day. The 12 constellation distributed on this trajectory is called the ecliptic 12 constellation, also called 12 constellation for short.
