So you’ve caught feels and maybe (just maybe) this could be LOVE. And what better way to find out if this cutie is The One than astrology?
Look: Most astrological compatibility resources focus explicitly on Sun signs, which are obvi based on your date of birth—but they don’t incorporate your birth times and locations. And you need all three—your date, time, and location of birth—to get your full birth chart. Because TBH, astrological compatibility is a lot more complicated than your Sun signs! While your Sun sign is super important and tells you about your identity, your Moon sign tells you about your emotional inner world, your Venus sign tells you about your attitude toward love and pleasure, your Mars sign tells you about your POV on passion, your Saturn sign tells you about how you experience commitment…which are all v important in relationships!!!
Basically, the more info you have about someone’s birth details, the more you can find out about how your birth charts vibe romantically. Synastry, aka the art of comparing two people’s birth charts to assess their compatibility and relationship, can go mega deep. (Trust me, I’ve jumped down that rabbit hole many times.)
Now, let’s just say you don’t have all those extra birth deets but you still know your sweetie’s birthday (including the year). While you won’t get some details of their birth chart, like their Rising sign, just a b-day can still give you a ton of info—like their Venus and Mars signs. Check out a handy synastry calculator like this one to do the hard work for you.
Here are some possible astrological connections that show if your connection is ~out of this world~. FYI: You don’t need all of them to have a meaningful relationship—even just a couple can give you eternal heart-eyes.
Compatible Moon Signs
An extremely important factor when looking at a relationship is determining if your Moon signs are aligned. In a sense, it can help you to know how each processes your feelings on a deeper, internal level. For instance, if two people have the same Moon sign, this means that they often share similar emotional rhythms and at the end of the day have an easier time finding a sense of peace and unity.
If two people have the same element for their Moon signs, this can also help them ebb and flow more easily, too. Like, if you and the boo both have fire sign Moons—like an Aries Moon and a Leo Moon—you’ll crave similar levels of passion and intensity and get excitable more easily. Two people with earth sign Moons—like a Virgo Moon and a Taurus Moon—will revolve around having a sense of emotional stability and security together. If two air sign Moons—like a Gemini Moon and a Libra Moon—are chilling, then this also brings an intellectual flair to how they align, plus a heightened need to chat, chat, chat. Finally, two water sign Moons—say, Scorpio Moon and Pisces Moon—are both immensely sensitive, bringing the pair a truly empathic and compassionate approach to how they align with one another at a soul level.
Another factor to note is that because the Moon and planets move day by day, those with Moon signs in the same zodiac sign or in the same element will likely experience astrological aspects around the same time, too, revealing that you’re often in a similar pattern! So a similar rhythm of feeling feisty, moody, somber, or joyous will also often overlap.
Ascendant-Descendant Match
If you can get all the info for both of your birth charts, you’ll be able to learn just how perf your match is (or isn’t). In astrology, your Ascendant (aka your Rising sign) is opposite something called your Descendant. To find your Descendant, just look for the zodiac sign opposite your Rising sign, or six signs away on the zodiac. So if your Ascendant is Virgo, your Descendant is Pisces, and vice versa.
The Ascendant and Descendant mirror each other, so when you find someone whose Ascendant is the same as your Descendant, opposites attract, bb! That means that if you’re a Virgo Rising and your crush is a Pisces Rising, you’re compatible.
Even if it’s not the exact opposite match, two Ascendants that are in harmony with each other (like in the same element—for example, you’re a Virgo Rising and they’re a Taurus Rising, both earth signs) can denote a total easy-breezy connection that supports the other, no matter what.
Congenial Elements
About those elements! Y’know how some people just “get you”? Well, it might not be obvious from your Sun signs, but you may actually have a lot of planets in congenial elements, meaning you just sorta vibe on the same frequency. While you’re not totally the same, your differences mean that you complement each other super well. Fire signs + air signs = “Let’s get lit!” and earth signs + water signs = “Let’s flow.” So if you’re a Taurus (an earth sign) and your crush is a Cancer (a water sign), then heyyy, you’re a great match. Same goes for fire signs (like Leo) and air signs (like Gemini).
It’s also not just about having your Sun signs in compatible elements, although that is a good thing. But what about your Mercury? Mars? Venus? This can add attraction and synergy. Maybe your Mercury is in emotional Pisces while your S.O.’s is in intense Scorpio. Scorpio and Pisces are both water signs, so you’re a fit!
Take a look at your birth charts. If you have a lot of planets in fire signs (like, your Mercury is in Aries, your Moon is in Sagittarius, and your Jupiter is in Leo) and bae has a lot of planets in air signs (like, their Venus is in Gemini, their Saturn is in Aquarius, and their Moon is in Libra), you probably get along like…well, like a house on fire. But in a good way!
Sun-Moon Aspects
Your Sun sign is def ~major~ because it’s tied to your ego and life force, but your Moon sign is also v. important because it’s connected to your inner emotions and soul. Having these two luminaries interacting in your charts is fab because it shows strong psychological and emotional attraction. This can be intense, but TBH, it often leads to a meaningful and supportive connection.
Take a look at your Sun sign and your crush’s Moon sign. If they’re in the same sign (aka “conjunct”), two signs apart (aka “sextile”), or four signs apart (aka “trine”), that’s major compatibility, babe.
For example: Your Sun is in Scorpio and their Moon is in Scorpio. Or your Sun is in Scorpio and their Moon is in Capricorn (two signs away from Scorpio, aka sextile). Or your Moon is in Scorpio and their Sun is in Cancer (four signs away from Scorpio, aka trine). You get the picture!
Venus-Mars Links
Whoa! When Venus, ruling love, connects to Mars, ruling passion, you know that there will be uh-mazing chemistry. If these planets are dancing together between your charts, you’ll also feel that you’re living a cosmic romance.
Pleasant interactions between these planets (like those conjunctions, trines, and sextiles I mentioned) lead to a peaceful and sweet rapport, but more challenging aspects (like squares, aka three signs apart, or oppositions, aka six signs apart) turn up the heat (hint, hint: mind-blowing sex).
An example: Your Venus is in Libra, and their Mars is in Libra. That’s a conjunction. Nice! Or maybe your Mars is in Virgo and their Venus is in Capricorn. That means your Mars is trine their Venus, which makes for a sweet, strong match. Or mayyybe your Venus is in Scorpio and their Mars is in Aquarius. That’s a square, indicating astrological tension…and ~astrological tension~. In a hot way!
Outer Planet Connections
The outer planets—shout-out to Jupiter, Saturn, Uranus, Neptune, and Pluto—can also influence our relationships, although often a bit less directly than the inner planets (which astrologers call “personal planets” because they affect us so personally!).
When outer planets in one person’s chart link with anything else in the partner’s astrology, you tend to have a transformative effect on each other. You could change each other’s lives in subtle or even massive ways. Think: Your Moon is in Leo and your S.O.’s Jupiter is in Leo (a conjunction), or your Venus is in Aries and your S.O.’s Pluto is in Sagittarius (a trine). Extra special here is Saturn, which is the planet associated with commitment, structure, and hard work. Your Saturn sign and how it connects with your partner’s birth chart can tell you a lot about how you’ll work in a long-term relationship.
Planets in Important Houses
In astrology, we often look at how two birth charts interact, so when you know your + the boo’s actual birth times, you will be able to run a map of where one another’s planets fall. In astrology, everyone's birth chart is divided into 12 houses, each of which rules a different area of life.
For instance, if you have any planets that pop up in one another’s 1st house, you’ll have a strong sense of unity and be able to understand one another better (especially if it’s a luminary like the Sun or Moon or a planet like Venus or Mercury). Any personal planets that land within one another’s 5th house, which rules passion, romance, and fun, also bring a deeply sexy and jovial nature to the rapport. Got planets in one another’s 7th house? Wowza! That’s mega important and brings a strong bond. Any 8th house planets can bring intensity and an all-or-nothing feel to a connection, while 11th house planets may help you to align more around your goals and even see each other as not just lovers, but also friends.
Extra credit: Look to where Jupiter and Saturn fall in each other's houses. Jupiter being present will bring expansion, luck, and joy to each other, whereas Saturn can bring stability and longevity.
Juno = Asteroid of Marriage
Yes, asteroids can influence our relationships too! Enter Juno, the asteroid of marriage and union. Juno illuminates how a person looks for devotion and affection. Take a peek at each other’s Juno signs. Just like the other planets, conjunctions, sextiles, and trines mean good news for compatibility. BTW, even just learning someone’s Juno sign will teach you a thing or two about their expectations in a forever boo. And no matter what your own birth chart looks like, that’s v important info to have.
