There were several zodiac signs before ancient times.
Of the 88 constellations currently in use, 50 are derived from Ptolemy constellation. Isn't it strange why there are 50 and Ptolemy only has 48? That's because Ptolemy's South Star was disassembled into three independent constellations, namely Carina, Stern and Vela. With the progress of science and technology, 15 ~ 17 century, the era of great navigation is surging. Sailing on the sea in the southern hemisphere, the sailors found that many stars in the sky were not in Ptolemy, and Ptolemy was not enough. This makes navigators who rely on constellations to identify their directions feel distressed.
It turns out that civilizations such as ancient Babylon and ancient Greece are all in the northern hemisphere, and people there can't observe the stars that can only be seen in the southern hemisphere. Finally, in 1603, the German astronomer John? Bayer added 12 Southern Constellation, which helped navigators to identify the direction. Then in 1690, polish astronomer John? Jahannes Hewelius found out. To 1763, Nicholas? Llakaj has found the 14 constellation. Since then, new constellations have been discovered and supplemented continuously, reaching above 100 at most.
1922, the International Astronomical Congress finally decided to divide the whole day into 88 constellations. By 1930, the boundaries of these constellations were formally defined by the International Astronomical Union. Since then, all the stars, nebulae and galaxies except the sun belong to a specific constellation and have their own homes.
