Sun
This is probably the most well known star. It is the star in which all planets orbit around. For a long time people believed in geocentric theory or the theory that everything revolved around the Earth. This was until the discovery of the heliocentric theory was made. This is the theory that everything revolves around the sun. Although massive, the sun actually does not compare to the power of many other stars. A fun fact about the Sun is that one million Earths could fit in it. Another fact about the Sun is that it is estimated that the Sun is halfway through its lifetime.
In Ancient Egypt they believed in a Sun god Ra. This god received the highest status. In the ancient Aztecs sacrifices were made for the Sun gods. Then in Japan a Sun God played a major role in mythology and was said to have supreme power over the land.
