Sun in Aries, Moon in Gemini Compatibility

Here’s a combustible mix. Gemini’s airy curiosity fans the flames of Aries’ initiative. This couple will certainly maintain each other’s interest, but they may have trouble settling their frenetic energy into a structured relationship.

Sun in Aries wants to experience risk. His purpose is to build courage in all areas of life, including his relationships. He can be blunt and pushy, but this just means he’s asking to be challenged. Instinctive action is what drives him, and he has no patience for subtleties. Sun in Aries wants a partner who forces him to experience extremes. If he’s not challenged, he’ll create conflict with temper tantrums or pointless arguments.

Moon in Gemini needs to bond by communicating. Sharing experiences with a companion is what she’s all about, and this does not necessarily mean deep, emotional discussions. For Moon in Gemini, lighter feels more comfortable because she needs to learn at an accelerated pace. This can make her a restless, emotionally scattered partner if her relationship becomes stale.

These two will set off on an adventure that never ceases. Sun in Aries’ drive for challenge will be easily supported by Moon in Gemini’s need for variety. She’ll keep him guessing as she regularly switches emotional channels. Moon in Gemini may frustrate Sun in Aries when she wants to talk (about everything) and he wants to take action. But Gemini will be unperturbed by Aries’ bluntness because she intellectualizes her emotions. As long as she’s given a forum to say what she feels, they’ll quickly move through most disagreements.

The issue with this pairing is lack of stability. Unless there are grounding influences in their charts, this couple may never settle into a long-term relationship. But stability isn’t for everyone; sometimes two people just need an encounter to wake each other up.

  1. Why is it important to use the mans sun sign and the woman’s moon sign to show compatibly? If two sun signs are compatible and two moon signs are compatible, why mix it up for one sun and one moon? My partners sun sign is compatible with mine, but my moon sign is not compatible with his sun. I’m confused.

  2. compatibility* Sorry -typo,

    I’m just using the gender assignments for clarity, because the Moon is female energy and the Sun is male energy (no matter if the owner of the Sun or Moon is male or female). But the Sun/Moon sign mix could belong to either sex (or same sex relationships).

  4. Oh, I don’t think you understood what I meant. I have no problem with the gender association, it’s just that I’m a Leo Sun/Gemini Moon and the guy I like is Aries Sun/Virgo moon. I’ve always been told that Leo and Aries is a good match, but my moon sign does not seem to mesh well with his sun sign at all. I just wanted to know why it was important to match one moon sign with a sun sign for compatibility versus sun/sun moon/moon. I saw the same thing on here with Taurus Sun/Sagittarius Moon. A friend of mine is a Capricorn with a Sag. moon and his mate is a Taurus Sun/Cancer moon. Their sun signs are said to be compatible but the moon sign with the sun is rocky…but describes them perfectly, so I’m confused. Is it more important to combine a sun with a moon for love rather than moon/moon and sun/sun?

  5. Oh wait —maybe you did answer my question. It’s the energy that determines a good relationship? Because I’m telling you—on paper, me and the guy I like are perfect for each other…same for my friends, but all the problems you describe for both couples are spot on and I just wanted to know how that gets determined by only using a sun sign for one partner and the moon for the other.

    You have to analyze both charts in their entirety. The Sun/Moon sign combos are only brief overviews. But since the Sun and Moon are such dominant energies, compatibility issues between them are very noticeable.
