The power of sister signs

Romantic comedies would love you to believe that opposites attract, but what does astrology have to say about that? There are several ways to measure the zodiac compatibility of two people, in both love and friendship, and chances are, you’ve checked your horoscope to see if you’re a perfect match with someone. Well, even if you know all about your rising signs and your luckiest months of the year for relationships, you might be missing something if you haven’t considered sister signs.

Every zodiac sign has a corresponding sign that shares its experience and provides an alternative view of the world that challenges them to grow. Your sister sign often contains qualities that you might feel you lack, and they encourage you to strengthen those sides of your personality. When the sister signs get together, the relationship will challenge both people to compromise and see things from the other’s perspective.

So what is a sister sign, exactly?

A sister sign is the zodiac sign that sits opposite yours on the astrological wheel. “The sister-sign pairings always sit six signs away from one another, or 180 degrees apart on the zodiac wheel, in an aspect known as an opposition,” explains Brittany Beringer, a mystic and astrology writer. “Because they’re directly across from one another, they share a similar outlook or attitude toward love, but differ in the way they express or experience it.”

Each sister-sign couple shares a complementary zodiac element (water and earth; fire and air), which causes the initial attraction. But these pairings also share the same zodiac polarity (cardinal, fixed, mutable), which is why the sister signs can frustrate each other as well.

There are six pairs of sister signs in astrology:

  • Aries and Libra
  • Taurus and Scorpio
  • Gemini and Sagittarius
  • Cancer and Capricorn
  • Leo and Aquarius
  • Virgo and Pisces

Are sister signs a good match together?

If you’re planning to date someone with your opposite sign, you need to be ready to compromise a lot. Each of the sister-sign pairings has a strong attraction to each other, and their shared axis in astrology means each person in a sister-sign relationship has something the other person needs. You will challenge each other and frustrate each other from time to time, but the passion between sister signs is what fuels your love. A cooperative relationship between sister signs will challenge and elevate each individual in the relationship and lead to a strong, lasting bond.

The friendship between sister signs is about as natural as it comes. In fact, it’s not uncommon to find a group of friends who all share sister-sign pairings. When you befriend your sister sign, get ready for plenty of laughs, adventures and deep conversations. These are the people who you feel truly appreciate and understand you. It can almost feel as though you’ve found your long-lost twin or may even feel as though you knew this person in a past life. Sister signs are built to challenge and bring out the best in you. Your opposite sign will always look out for your best interests and isn’t afraid to tell it like it is when you need it.

Aries and Libra

Let’s start with Aries’s sister-sign pairing with Libra. People born under both these signs are natural-born leaders who aren’t afraid to chase their dreams, but their motivations differ. “Aries is a fire sign, so they are very concerned with self-image. They make things happen based on self-satisfaction, like their ambition and passions,” says Beringer. “On the other hand, Libra, who is a sociable and relationship-oriented air sign, is more interested in the impact they make on others. They’re motivated by connection.”

Because of their different approaches to success, it’s not uncommon for power struggles to arise between these signs. But if they can come together to support each other’s career aspirations and goals, nothing can stand in the way of these two building an empire. This power couple knows how to command attention anytime they enter the room, and they’re always on the cutting edge of what’s trendy and fashionable.

Taurus and Scorpio

Taurus and Scorpio are both known for their depth and intensity in relationships. The energy between Taurus and Scorpio is all about desire and power, which they seek out in different ways. “For Taurus, these desires hinge on value—both within the self and in the material sense. They feel powerful when they’re secure in themselves and when they have tangible financial and material possessions they deem worthy,” Beringer explains. “For Scorpio, the thirst for power lies in a more spiritual way. They seek power in the sense of authority and dominance.”

Taurus and Scorpio might be the two most stubborn signs of the bunch, so finding common ground between them might take some time. As fixed signs, neither is likely to budge first. However, when Taurus and Scorpio come together successfully and their lives are moving in the same direction, they have a romantic or deeply intimate relationship that feels unshakable. As these two get more comfortable with each other, Taurus will help Scorpio feel secure enough to share their feelings, and Scorpio will help Taurus open up and learn to trust people.

Gemini and Sagittarius

Gemini and Sagittarius just may be the most similar sister-sign pairing of the bunch. As the mutable signs, they are very free-thinking and intelligent zodiac signs, and they are fueled by their shared love of the unknown. “Geminis have the fortitude to investigate and ask questions nobody thought to ask. Their restlessness often causes them to take shortcuts,” says Beringer. “Sagittarius sees life experience as the greatest teacher and will weather the storm if it means they’ll grow as a result.”

Neither of these signs likes to stay put in one place for too long, which is why they’re naturally drawn to each other. They’re happy to keep things casual and see where life takes them without much expectation. However, their love of freedom is one of the reasons these two have trouble committing. It takes the perfect timing, a deep connection and some serious conversations for Sagittarius and Gemini to agree to settle down together. But if they can pull it off, it is pretty much guaranteed that love will quickly become their greatest adventure of all.

Cancer and Capricorn

Cancer and Capricorn represent the axis of commitment and devotion. As cardinal signs, they share strong convictions and a desire to make their mark on the world. Both are dutiful and committed to taking charge in whatever life throws at them. “Cancers rely on their intuitive hearts and move with empathy. Their leadership often comes from a sacred place,” says Beringer. “Capricorns show authority in a public-facing way. They use logic to problem-solve and lead in a more concrete way.” If Cancer seeks to provide for others by offering emotional security and empathy, Capricorn provides security by bringing order and structure.

A successful relationship between Cancer and Capricorn is built on deep trust and mutual respect for the other person. Both of these signs understand the work and sacrifice it takes to build a lasting legacy, but they deal with the stress in different ways. Earthy Capricorn is known to be less emotional and more logically driven, while Cancer is famous for being sensitive and moody. This disconnect can be a sticking point in relationships, but if both partners can learn to be vulnerable with the other, these two can build a lasting relationship that is both emotionally and financially enriching.

Leo and Aquarius

Though they might seem completely incompatible at first, Leo and Aquarius actually complement each other incredibly well. Both signs are known for their confident and self-assured attitudes and can work together to challenge the status quo. “Leos are champions of authenticity and crave to express themselves freely and openly. They’re concerned about how they see and experience the world, and how the world responds,” Beringer says. “Aquarius is more interested in how they fit as an individual in society. They’re about individual freedom, but it’s concentrated on how they synergize with the world around them.”

As the bombastic showstopper of the zodiac, Leo has a feisty and fiery energy that is hard to ignore. People born under this sign draw attention wherever they go and always seek to live their lives through creative and personal expression. Aquarius, on the other hand, has a reputation for being a bit more introverted and selective with who gets their attention; that means they don’t play games in love and are usually very direct in how they feel. Aquarius may be intimidated by Leo at first or feel as though they’re doing too much, but Leo’s warm and bright personality knows how to coax Aquarius out from under their shell and help show the world their truly unique talents. Finding your sister sign is a smart way to use your zodiac sign to be happier.

Virgo and Pisces

As mutable signs, these two are flexible in how they approach life. Think of Virgo and Pisces as the connection between the physical world and the dream realm, respectively: Both these signs know how to tap into their intuition with ease, but their insights come from different places. “Virgos are tethered to material connections, like reputation, status and relationships with others—ultimately, they take notice of small details on the surface,” says Beringer. “Pisces are more acquainted with the things beyond that, like our subconscious, abstract ideas and spirituality. They take notice of what’s unseen.”

Virgos and Pisces make a terrific match in love if you can get them to get on the same wavelength. They each know how to approach difficult conversations and challenges while being open-minded about their partner’s perspective. They’re also both givers in a relationship and will go above and beyond to get the details just right for their partner. The real trick is getting them to admit their feelings for each other. Neither is likely to make the first move, but if you can encourage each half of this pair to say what’s on their mind and stand firm in what they want, a beautiful relationship will blossom between them. These inspirational zodiac quotes just might help them get on the right track.
