Your moon sign (which you can calculate here) is determined by the position of the moon in the sky at the moment of your birth, and it speaks to your emotions, intuition, and inner world. And what’s more romantic than a couple who understands the deeper layers of each other’s psyche? It speaks to your personal, unseen world—your subconscious. And it has everything to do with your emotional needs. As mbg’s resident astrologists the AstroTwins explain, “Your moon rules your emotions, your responses, even what you’re drawn to sometimes. It’s your internal life,” adding, “Moon signs are kind of everything for compatibility.” The twins say that the people you get along with best, particularly in a romantic context, often have the same or a compatible moon sign to you. These are the folks you connect with on a deeper emotional level, which fosters an understanding that simply can’t be achieved with everyone. While looking into sun sign compatibility is still worthwhile, the twins note it’s more general and superficial than moon signs: “The moon sign is what’s hidden. It’s what we don’t necessarily see, so it’s more important for the longevity of the relationship than if you’re the same on the outside. Your moon sign is what really emotionally drives you.” As for air moons, “They’re always on the go, so an earth moon will ground you,” the twins say. “If you’re ready for that, then great—but if you’re not, then you’re gonna feel stifled.” Earth moons will get along well with other earth moons and water moons, but again, fire and air may not mix well. And for water moons, you guessed it: They like other water moons and earth moons, but air and fire moons might clash. Even if your moon signs aren’t typically thought of as compatible, the twins do note that, of course, a healthy relationship is still possible. “You’re just going to have to recognize you may have some differences,” they say, adding the balance can actually be beneficial. “You may provide something for the other one that they don’t have.” Here’s a deeper dive into moon sign compatibility, sign by sign. The twins note Aries moons are prone to falling fast, but add the flame that burns twice as bright burns twice as fast. These folks can have lots of intense, short-lived flings, and it takes a special, exciting soul to tie them down. They’ll do well with another fire moon, but the emotional heaviness of water moons may just put out their fire. They crave a partnership with routine, stability, and tradition but could do well to spice things up once in a while, for the sake of the spark. They’ll do well with other earth moons, and the twins note air moons might be a bit too “out there” for these grounded souls. While they can be indecisive in love, these folks want to find their twin flame—and badly, the twins tell mbg. The best way for them to find their match is to meet a like-minded soul who can reflect back all the thoughts bouncing around their head. As such, air moons are a great match; Earth moons might feel too slow and steady for them. They’re very sensitive, as well as intuitive, as a water moon, and while they’re natural caretakers, they need a hand too, sometimes. As such, water moons make a great pair with a Cancer moon, but the intense and blunt nature of fire moons may be too much for these sensitive spirits. If you can give Leo moons the absolute adoration they crave, they will reward you with loyalty, trust, and a deep and passionate relationship. Fire moons will do the best in love with Leo moons, but like Aries, they may feel extinguished by water moons. They’re guarded souls, and they don’t let just anyone in, sometimes having difficulty receiving help from others. But in a relationship, they’ll do anything for the person they love. Their best odds are with another earth moon. Air moons, with their heads in the clouds, can feel a bit too lofty for their taste. The twins add that the moon in Libra makes for a very accommodating person, helping them to thrive in relationships and make an excellent partner. These romantic moons will get along with other air moons, but they may find earth moons don’t match their airy energy. Once they do, though, Scorpio moons are loyal to the end, and they expect the same devotion from their partner. While they may have a hard time opening up and being vulnerable, the people most likely to help them do so would be other water moons. Fire moons, on the other hand, will probably not mesh with their emotional intensity. Nevertheless, if they feel like a potential partner can help them grow and expand while giving them the freedom they so desire, they can make a very fun and exciting lover. They’re passionate, open-minded, and free-spirited, so fellow fire moons do well with them in relationships. And like their other fire counterparts, they may feel overwhelmed by water moon’s emotional depth. In relationships, they can be a bit forlorn, and even melancholy, which can make them seem distant, but you can be sure they’ll put in the work to reach whatever goals you have together. Other earth moons will understand their structured and methodical nature, but air signs often will not. This can make them difficult to pin down in a relationship, as they greatly value their freedom. In fact, it’s not uncommon to see these folks in open relationships or a friends-with-benefits situation. If and when they do find one person to “settle down” with, they will always require a degree of space. Fellow air moons can appreciate this about them, but earth moons may find it hard to truly understand them. Pisces moons are also healers, so having someone around to lend a hand when they’re drained will greatly benefit them. You guessed it—fellow water moons are the ones best suited for the job, while fire moons may feel too draining or chaotic to these sensitive souls.
