The signs and houses that Moon and Venus occupy say a great deal about where and how this trine operates. Moon in Capricorn trine Venus in Taurus expresses warmth through reliability and physical comfort; Moon in Gemini trine Venus in Libra does it through conversation and a light touch. The element the two share tells you the medium: earth trines show it in the material world, air trines in words and ideas, fire trines in enthusiasm and directness, water trines in feeling and intuition.
A Sun trine Moon alongside this trine makes the whole emotional package easier still, which is either very good or a second reason to never look at what is uncomfortable. Mars's position matters too: if Mars is in hard aspect to either planet, the ease of the trine gets more complicated in moments of conflict or desire.
The houses Moon and Venus occupy point to where this trine does its most visible work. Moon in the 10th house trine Venus brings warmth into public life and reputation; Moon in the 8th house trine Venus brings it into intimacy and shared resources, which is a different kind of depth altogether.
Because Venus is never more than 48 degrees from the Sun, and a trine requires 120 degrees, Venus cannot trine the Sun. That means this Moon trine Venus exists independently of where your Sun falls, which is worth remembering: what you feel and what you love are connected regardless of your Sun sign's usual story about you.
