Constellations Knowledge Cards
This collection of Knowledge Cards presents a concise, informative look at 46 star groups. Each card has a chart of the featured constellation on the front; its position and area, brightest star and number of visible constituent stars, zodiac sign, and notes about its origin and history on the reverse. One card is a glossary of astronomical terms; another gives general information about the heavens.

With 48 fact-filled cards per package, Knowledge Cards are a great source of condensed information—all in a deck the size of a pack of playing cards.
