Ruling planet????

Hey can u tell me what's ruling planet or the most dominate planets in this chart. It's for my nephew. Thanks!

With cancer rising moon is the ruler of the chart. Moon is also one of the most important planetary bodies when it comes to an individual personality. It pertains to emotions and emotional needs, the subconscious, intuition and so on...

By the way: moon is in its own sign here which gives it an even more dominant position.

Sun - which is always a considerable influence - is in a trine with moon. Trines are very favourable, harmonious aspects. I think your nephew is an highly sensitive and receptive person and his outward persona is very in synch with his chore personality.
