<human>:  I have a question about the field of Astrology. Why is it that the Sun is in the sky?
<bot>: The Sun is in the sky because it is the center of the solar system. The Sun is the largest and brightest star in the sky, and it is the source of light and heat for the Earth. The Sun is also the source of the solar wind, which is a stream of charged particles that flows out from the Sun.
