Introduction to Astronomy
This textbook we are using as a guideline for topics to be covered in Astronomy was published in 1910 but is surprisingly up to date on what we understand about the basic concepts of Astronomy. Topics covered includes: Different Kinds of Measurement, The Stars and Their Diurnal Motions, Fixed and Wandering Stars, Celestial Mechanics, The Earth as A Planet, The Measurement of Time, Eclipses, Instruments and Their Use, The Moon, The Sun, The Planets, Comets and Meteors, The Fixed Stars, Astronomy and Nuclear Physics.

Astronomy is the scientific study of the universe as a whole, and of celestial bodies and the underlying physics governing those bodies. This Wikibook introduces the reader to that tapestry and the process that revealed it to humanity. It presents astronomy not only as a field of knowledge, but also as a human endeavor in science.
