Understanding Each Sign’s Ruling Planet

Each sign is ruled by a particular planet. The position of that ruling planet in your chart determines the quality of that sign’s energy.

Example: Your Sun is in Cancer
→ Cancer's ruling planet = the Moon
→ The Moon's position and condition in your chart determines
   how your Sun energy is expressed
