In Lesson 1, we explore the apparent motions of the stars, the sun, and the moon. We explain the apparent motions of the stars and the sun in terms of the motions of Earth: its daily spin on its axis, its annual orbit around the sun, and the long-term precession of its spin axis. We learn how length of day and the height of the sun in the sky at midday vary with season and latitude. We explore lunar phases, lunar and solar eclipses, and the cycle over which all eclipses repeat.
