About the Planet Cards
The game consists of 42 cards, with a picture and factual information about one celestial body per card. Facts such as that Saturn has a lower mass density than water, even though it is 95 times more massive than Earth. And that Venus is 687 degrees hotter than Pluto! In addition, you'll find cards describing the rules for the three variants of the game and an overview of where all the objects are located in the Solar System
