There are a few ways you can consider what makes two zodiac signs soulmates, according to astrology expert Imani Quinn. As she tells mind body green, she often finds that opposite signs (i.e., Aries and Libra, or Taurus and Scorpio) can offer each other a yin-yang balance that complements each other.

But beyond just opposite signs, she also explains that understanding your planetary ruler can help you find a soulmate too. For example, Gemini and Virgo are both ruled by Mercury, so they share their Mercurian qualities.

Lastly, she says, our Venus sign will heavily influence how we give and receive love, so one could argue that having compatible Venus signs is just as important (if not more important) as having compatible sun signs when it comes to romance. “It’s basically like your astrological love language, so if you just look at your sun sign, you’re seeing your character—but that’s not necessarily how you need to receive love,” Quinn explains.

And bear in mind that soulmates don’t always have to be romantic—and they don’t always last forever. Soulmates can be anyone from friends to family to teachers or mentors, and they’ll serve a purpose to your soul’s mission even if that means the relationship is temporary.

Additionally, if you want a full breakdown of your astrological compatibility with someone, comparing both of your birth charts (using synastry, aka relationship astrology) is the quickest way to understand how you and another person will match up.

Aries is a fiery, go-getting sign that’s ruled by Mars, the planet of action and passion. According to Quinn, they make a good pair with their opposite, Libra, because of their complementary energies.

And since Aries is ruled by Mars, she adds, they may also feel a connection with Scorpio. Even though Scorpio is considered to be ruled by Pluto in modern astrology, its ancient ruler is Mars, so these two share in their high energy level and sex drive.

Taurus is the steady yet sometimes stubborn Bull, ruled by Venus, the planet of beauty and pleasure. This sign’s opposite is Scorpio, and Quinn tells Mindbodygreen they make a good match because both are extremely loyal, plus Taurus is grounding while Scorpio wants to investigate the depths of life.

Being ruled by Venus, Taurus will also feel a soul kinship with Libra, which is also ruled by Venus. Both of these signs appreciate the beauty in simple pleasures, sensuality, and romantic expression, Quinn notes.

Gemini, represented by the Twins, is adaptable, quick-witted, and ruled by Mercury, the planet of information and communication. So it’s no surprise that this sign’s soulmates are the other mutable signs. (They need someone who can keep up!) Gemini’s opposite sign, Sagittarius, will have no problem adventuring and exploring with their Gemini counterpart, Quinn notes.

And with Virgo being ruled by Mercury alongside Gemini, they share in their intelligence, humor, and quick wit, so they’ll have a very strong mental connection and enjoy great conversations, Quinn notes.

Cancer is the sensitive and nurturing Crab, ruled by the moon. Its opposite sign, Capricorn, offers a lovely grounding balance to the stability Cancer craves, according to Quinn.

And speaking of stability, that’s one reason a Cancer-Taurus soulmate pair would be gratifying, as both signs enjoy cozying up at home and enjoying the simple luxuries of their own space.

Leo is the bold and proud Lion of the zodiac, ruled by the sun. Its opposite sign is Aquarius, and Quinn says these two can help push each other’s visions forward.

Being ruled by the sun, they also feel soul connections with Cancers, who ruled by the moon, which Quinn says allows them to embody the polarity of divine masculine and feminine.

Virgo, represented by the Virgin, is an analytical and dedicated sign that’s ruled by Mercury. Its opposite sign is Pisces, and Quinn tells mind body green that these two strive for perfection in different ways and can encourage each other to grow and evolve.

And with Gemini being the other sign that’s ruled by Mercury when a Gemini and Virgo come together, there’s sure to be plenty of laughs and stimulating conversation.

Libra is a peaceful and relationship-oriented sign ruled by Venus. Its opposite sign is Aries, and while they may be very different, Quinn says they complement each other well and can help each other find balance.

Being ruled by Venus, Libra also naturally clicks with Taurus, as both appreciate aesthetics, culture, being cozy, and enjoying the pleasures of life, whether simple or extravagant.

Scorpio is intense and deep, ruled by Pluto in modern astrology and Mars in ancient astrology. Its opposite sign is Taurus, with these two offering each other balance, transformation, and the loyalty that both require to feel secure.

And while Scorpio is technically considered to be ruled by Pluto nowadays, its ancient ruler Mars still has a strong influence on this sign’s energy, making them a natural soulmate for Aries, who is also ruled by Mars.

Sagittarius is adventurous and spontaneous and ruled by Jupiter, the planet of luck and expansion. Its opposite sign, Gemini, is one of the few that can keep up with Sag’s fiery energy, making them excellent soulmates.

Similarly, Aries can keep up, too. As Quinn tells mind body green, when you get a Jupiter-ruled sign and a Mars-ruled sign together, there’s no telling what these two will accomplish together.

Capricorn is hardworking and structure-oriented, being ruled by Saturn, the planet of discipline and responsibility. Its opposite sign is Cancer, with these two helping balance a need for structure and security with comfort and compassion.

And looking to Saturn, Quinn says, Aquarius was ruled by Saturn in ancient astrology, so even though it’s considered to be ruled by Uranus now, Capricorn and Aquarius can make serious progressive headway when they come together.

Aquarius is quirky and humanitarian-minded, ruled by the planet of innovation, Uranus. According to Quinn, when they match up with their opposite sign, Leo, they combine fiery passion with progressive air for strong forward motion.

And when Aquarius links with Pisces, the ethereal vibes will be strong. As Quinn explains, they’re both looking for spiritual expansion, and there’s nothing these two can’t uncover and discover together.

Last but never least, Pisces is a dreamy and whimsical sign ruled by Neptune. Its opposite sign is Virgo, Quinn notes, making these two a good pair for balancing seemingly opposing energies and motivations.

Sagittarius meanwhile, is ruled by Jupiter, which is the planet that ruled Pisces in ancient astrology. As such, according to Quinn Sag and Pisces together can make major manifestation magic happen.
