When did humanity realize that the Sun is similar to the night-time stars? I can find no reference to this in Wikipedia or anywhere else. It seems that ancient man thought that the Sun was unique of it's kind (similar to how we perceived the Moon before Galileo observed Jupiter in his telescope), and today we know that it is just an ordinary object such as the thousands that we see in the night sky. However, I can find no reference to when this transition in understanding came about, or how. Thanks.
