The Earth rotates about its axis and revolves around the sun.. We sometimes talk as though the Earth were fixed and the celestial objects (stars, sun, moon, planets) move around us.. This is based on antiquity and is not true but it is sometimes a good way to look at the situation.. This introduction to the night sky is for amateur astronomers who desire a deeper understanding of the principles and observations of naked-eye astronomy. It covers topics such as terrestrial and astronomical coordinate systems, stars and constellations, the relative motions of the sky, sun, moon and earth leading to an understanding of the seasons, phases of the moon, and eclipses. Topics are discussed and compared for observers located in both the northern and southern hemispheres. Written in a conversational style, only addition and subtraction are needed to understand the basic principles and a more advanced mathematical treatment is available in the appendices. Each chapter contains a set of review questions and simple exercises to reinforce the reader\'s understanding of the material. The last chapter is a set of self-contained observation projects to get readers started with making observations about the concepts they have learned. William Charles Millar, currently Professor of Astronomy at Grand Rapids Community College in Michigan, has been teaching the subject for almost twenty years and is very involved with local amateur astronomy groups. Millar also belongs to The Planetary Society and the Astronomical Society of the Pacific and has traveled to Europe and South America to observe solar eclipses. Millar holds a Masters degree in Physics from Western Michigan University. Observations of Indigenous People. Enabling people to track seasons when dependent on agriculture. The Moon’s cycle of phases. The seven days are named after the Sun, Moon, and five recognized planets in ancient times. Astrologers generally believe that the movements and positions of celestial bodies can inform them about events experienced on a human scale or that predictions can be made from them.. Astrology is the NONSCIENTIFIC study of the sky and celestial bodies..
