Birth charts can help you determine where you and your partner will see eye to eye and where you may have conflict.
You don’t have to be fully obsessed with astrology to know your “Big Three” — aka your sun sign, moon sign, and rising sign. Even the fairest weather horoscope reader likely knows where they fall with these key birth chart placements. And while knowing your sun sign, moon sign, and rising sign is a fantastic way to bolster self-awareness, they’re also a great jumping off point for understanding more about your compatibility with others. In fact, moon sign compatibility is especially useful when it comes to relationships.
While your sun sign speaks to your self-image, confidence and core identity, and your rising sign colors the image you project out into the world, your skills, and talents, your moon sign is your “emotional compass,” helping shape your inner world, emotional nature and needs, intuition and instincts, sense of security, and nurturing style and the ways in which you want others to nurture you. So, if you want to feel safe, seen, and supported in a relationship, it’s pretty crucial for your moon to connect in a positive way with your partner or friend’s chart. To help you out, read on for a comprehensive guide on how to find your moon sign, how to look for moon sign compatibility with a partner, and who you’ll click with best, based on your moon sign.
How to Find Your Moon Sign
The best way to learn your moon sign is by running your unique birth, or natal, chart. Some apps list out your astrological birth placements in a list format, but that won’t give you the most information or equip you for learning even more down the road. You’ll do best to cast a free wheel-style birth chart by inputting your birth date, time, and place. From there, you can find the moon and determine what sign it was in when you were born.
The fast and dirty way: Use a moon sign calculator.
What to Look for to Determine Moon Sign Compatibility
Once you know your moon sign, you’ll do well to note which element (fire, earth, air, or water) it falls under. That’s because two placements that fall in the same element are 120 degrees apart, which indicates an easygoing, harmonious bond.
Fire signs: Aries, Leo, Sagittarius
Earth signs: Taurus, Virgo, Capricorn
Water signs: Cancer, Scorpio, Pisces
Air signs: Gemini, Libra, Aquarius
Then, you’ll want to dive into something we astrologers call synastry, or the analysis of two birth charts to determine compatibility, challenges, and a variety of different dynamics. Except instead of doing a full-fledged comparison, you can zero in on how your moon sign is relating to other details in another person’s chart. Check for the following connections, which can speak to truly solid compatibility:
Your Moon Sign Conjunct or Trine the Other Person’s Moon Sign
If your moon is in the same sign or the same element as your partner’s moon, there’s sure to be a natural, flowing harmony within your emotional bond. Having the same moon sign means that you’ll see eye-to-eye on what offers you a sense of security and how you want to be nurtured by one another. And having moons in the same element says that your emotional needs are in sync. For example, if you both have grounded earth moons, you might show one another you care through acts of service or offering practical advice. If both of your moon signs happen to fall in fire signs, you show you care by being demonstrative about your feelings and taking bold action.
Your Moon Sign Conjunct or Trine the Other Person’s Sun Sign
First of all, notice if your moon sign is in the same sign as your partner’s sun sign (or vice-versa!), which indicates one of the most powerful, palpable connections possible between two people’s charts. That’s because one person’s self-image, core identity, purpose, confidence, and self-esteem (aka their sun sign) mirrors the other person’s emotional nature and needs. You probably feel like you’re two puzzle pieces meant to fit together.
Similarly lovely is when your moon sign is in the same element as your partner’s sun sign (and, again, vice-versa). For instance, if your moon is in social butterfly air sign Libra, and you’ve just hit it off with someone who was born when the sun was in curious, buzzy air sign Gemini, you’ll find it takes little to no effort to get on the same page emotionally.
Your Moon Sign Conjunct or Trine the Other Person’s Venus Sign
In astrology, Venus is the planet of relationships, and your Venus sign speaks to how you express yourself creatively, what you perceive as beautiful, your relationship to earning money, your experience of pleasure, and your demonstration of affection. See if your moon sign is in the same zodiac sign as your partner’s Venus sign or in the same element (and therefore, trine) — or your Venus is in the same sign or element as their moon sign. If so, the way one of you emotes is aligned with how the other person relates, which can make for pretty sweet chemistry between you.
Who You’re Most Compatible With, According to Your Moon Sign
Read on for what to look for in a partner when it comes to both general traits and their birth chart placements.
Aries Moon
Born with your moon in the go-getter Mars-ruled fire sign, you process your emotions by taking bold action, generally at the speediest possible pace. You’re passionate, impulsive, playful, competitive, and even a little bit innocent and child-like in how you experience your feelings. You’ll connect best with someone who has their moon sign, sun sign, and/or Venus sign in Aries, as well, or one of the other fire signs: confident, action-oriented Leo and adventurous, unfiltered Sagittarius.
Taurus Moon
You’re pleasure-seeking, luxury-loving, grounded, sensual, and slow, steady, and deliberate when showing how you care, thanks to your moon falling in the relationship-oriented Venus-ruled earth sign. You need to feel like you can take your time getting into any relationship, but once you’re in, you’re all in. Look for someone who has their moon, sun, or Venus sign in Taurus, service-focused, sensitive, and also pragmatic Virgo, or goal-oriented, industrious, and similarly unhurried Capricorn.
Gemini Moon
Born when the moon was in the communicative Mercury-ruled air sign, you find comfort and security through constantly seeking and disseminating new information, learning, and socializing with others. The energy you bring into your emotional bonds is highly cerebral, and you often like to talk or think through how you’re feeling in order to better understand it. You click with people whose moon, sun, and/or Venus sign is in Gemini, as well as balance- and beauty-loving Libra or friendly, rational, community-oriented Aquarius.
Cancer Moon
With your moon sign in the zodiac sign it rules, and therefore, is at home in, you’re highly emotionally intelligent, sensitive, sentimental, heartfelt, and can’t help but show up for others through caregiving. You feel most secure when enjoying a peaceful, calm home life and healthy bonds with family. You’ll find you have the most harmonious connections with people whose moon, sun, and/or rising sign is in Cancer, intimacy-seeking and similarly family-oriented Scorpio, or empathic, artistic Pisces.
Leo Moon
Born when the moon was moving through the confident sun-ruled fire sign, you’re dynamic, charismatic, optimistic, fiercely loyal, and super-showy when it comes to working through and demonstrating your emotions. You’re naturally warm and loving — basically human sunshine — which can spur people to gravitate to you. But you’ll feel the most sparks with someone whose moon, sun, and/or rising sign is in Leo, as well as playful, fiery Aries or wanderlust-filled, philosophical Sagittarius.
Virgo Moon
When bonding with and nurturing others, you’re service-oriented, rational, sensitive, and adept at research and communication, because your moon sign is ruled by information-gathering Mercury. Truly nothing brings you more joy and comfort than being helpful to others, and you’re also cerebral and grounded in how you go about showing you care for your nearest and dearest. You’ll connect with someone whose moon sign, sun sign, and/or rising sign is in Virgo or down-to-earth, sensual Taurus or hardworking, driven Capricorn.
Libra Moon
You do your best to promote balance, steer clear of conflict, and foster lots of fulfilling relationships — which you prefer to enjoy one-on-one — because you were born when the moon was in elegant Libra, ruled by sweet Venus. Immersing yourself in beautiful spaces and harmonious social time both contribute to your emotional well-being. You’ll feel most at ease with someone whose moon sign, sun sign, and/or rising sign is in Libra, too, or fellow air signs, communicative, on-the-go Gemini and group-oriented, future-minded Aquarius.
Scorpio Moon
You’re intensely intimacy-seeking, devoted, private, and have an unflagging reverence for family life as a result of your moon being in powerful Scorpio, co-ruled by go-getter Mars and transformative Pluto. You pursue the emotional attachments with laser focus, and once you’ve made an impactful connection, you’re fully committed. You also seek to feel transformed by your bonds. Chemistry is inevitable when you connect with someone whose moon sign, sun sign, and/or rising sign is in Scorpio, as well, or in sentimental, emotionally intelligent Cancer or dreamy, spiritual Pisces.
Sagittarius Moon
You find comfort and inner peace by getting out into the world, soaking up new information, and exchanging eye-opening philosophies with others, thanks to your moon in lucky Jupiter-ruled Sagittarius. Buoyant, entertaining, and unfiltered in how you nurture others, you’re a free spirit at heart. You’ll hit it off most with people whose moon sign, sun sign, and/or Venus sign are in Sag, as well as independent, go-getter Aries or sunny, spotlight-loving Leo.
Capricorn Moon
Pragmatic, serious, and industrious, given that your moon is in the sign ruled by Saturn, the planet of hard work and commitment, putting your nose to the grindstone to reach the peak of whatever mountain you’ve set your sights on makes you feel emotionally centered. You care for others by supporting them in their own aspirations and offering practical words of wisdom. You’ll connect best with someone whose moon sign, sun sign, and/or Venus sign is in Cap, too, or steady, down-to-earth Taurus or detail-oriented, routine-loving Virgo.
Aquarius Moon
Because you were born when the moon was in the rational, individualistic, science-minded air sign, ruled by Uranus, the planet of innovation, and Saturn, the planet of boundaries, you find comfort in the ability to march to the beat of your own drum. You value eccentricity, future-mindedness, and platonic connection and are deeply humanitarian. For that reason, you’ll do best bonding with someone whose moon sign, sun sign, and/or Venus sign is in Aquarius or a fellow air sign like friendly, cerebral Gemini or balance- and justice-seeking Libra.
Pisces Moon
Artistic, sensitive, empathic, and perhaps a bit psychic are all characteristics associated with your moon sign, which is ruled by Neptune, the planet of spirituality, and Jupiter, the planet of abundance. You can’t help but idealize your nearest and dearest and you show you care by providing a gentle, loving shoulder while tuning into opportunities to offer emotional healing and support. You’ll find a great deal of satisfaction from bonds with people whose moon sign, sun sign, and/or Venus sign in Pisces, too, or another water sign like family-oriented, compassionate Cancer or deeply emotional, magnetic Scorpio.
