It concentrates on the Sun, Moon, the five bright planets, and on the 23 brightest stars, which are visible from just about anywhere. The book concludes with bright ephemeral phenomena: meteors, comets, and exploding stars. The concept is a platform for introducing the reader to the wonders of the nighttime and daytime skies and serves as an introduction to general astronomy."
