How much did the Aztecs know about astronomy?

That the Aztecs had abundant astronomical knowledge is a known fact. Astronomy had such an influence on their culture that most of their traditions are based precisely on the behavior of stars, planets and other spatial notions.Aztec astronomy and architecture
It is impossible to talk about astronomy in the Aztecs without mentioning its relationship with architecture. This town built great buildings, especially pyramids, in honor of the sun, the moon and other stars, as a way to thank the stars and glorify them. In them sacrifices were made, which according to their magico-religious thought ensured the correct astral functioning and the bonanza of the planet. Many of these spaces were also observatories, from where they tracked the celestial movement, as did other Mesoamerican peoples. The work was done by nobles and priests, who performed nocturnal rituals that allowed them to define their calendars. The temples were high places to follow the departure and sunset of the stars.
