These 19th century French constellation cards show each individual star marked with a hole through which light shines. Astrologically, each zodiacal sign has its own properties and its own friendships and enemies within the zodiacal circle. Each sign is also ruled by a planet, which similarly has its own properties, friendships and enemies. So, for example, a person born while the Sun is passing through Leo is supposed to be kingly, like a Lion.
