History

Since ancient times, the Sun has been a powerful symbol and an object of worship in many cultures worldwide. Early civilizations, such as the Egyptians, Greeks, and Aztecs, worshipped the Sun as a god or deity because of its importance for agriculture and survival.
In Japan, the Sun holds special cultural significance. The Japanese flag features a red circle symbolizing the Sun, known as the "Hinomaru." The Sun goddess Amaterasu is a central figure in Shinto mythology and is considered the mythical ancestor of the Japanese imperial family.
Scientifically, the Sun has been studied extensively. It is a massive ball of hot plasma, composed mainly of hydrogen and helium, generating energy through nuclear fusion in its core.
