Hubble Star Cards includes some basic information, such as distance to objects in space. Players shuffle the cards and divide up the cards evenly. Without looking at the cards, players draw cards from their stacks and place them in the center. Using the distances provided on the cards, players gain more cards if their card is farther away than their opponent’s. The reverse of this can be played where objects closer to Earth, such as Jupiter, would beat out a galaxy much farther away.
