From the moment you initially discovered how to decipher your horoscope, chances are you looked to astrological compatibility readings to comprehend how you would fare with your infatuation. And in the present day, it’s more about how you will form a connection with that attractive match on Bumble or even your long-term romantic partner. However, examining how two signs connect and clash can be beneficial for a variety of relationships, from your friendships to your siblings to your colleagues. And if you consistently find yourself collaborating on professional projects with Cancers or instantly hitting it off with Aquarians, you might be maximizing the potential of your astrological sister sign.
Here, you will find the fundamentals regarding sister signs, often referred to as astrology’s polar opposites or polarities.
What Are Sister Signs?
In simple terms, a sister sign is the sign located on the opposite side of the zodiac from your own. Seeking to comprehend your astrological counterpart, or sister sign, can help you identify qualities that you may be lacking but could learn from individuals in your life who possess them, owing to their astrological placements in that sign. Although we often associate “opposite” with opposition or tension, the term holds a much more intricate meaning in astrology.
Certainly, any opposition can be exasperating, challenging, or even lead to a lot of eye-rolling (similar to the most intense argument you ever had with a sibling or close friend). However, if you are willing to work with it, an opposition can also establish the foundation for profoundly rewarding self-improvement, common ground, and equilibrium. In other words, individuals you encounter who possess a significant amount of your sister sign in their birth charts could be the ultimate complement to your personality.
Qualities and Elements Shared by Sister Signs
Take a look at the sister sign that corresponds with your sun or rising sign. Then consider your moon sign and possibly even all of your significant six (meaning your sun, moon, rising, Mercury, Mars, and Venus). It is possible that you frequently connect with individuals who have the sister sign to your rising sign (as that sign governs your seventh house of partnership) or natal Venus (the planet of relationships).
Located six signs or 180 degrees apart from each other on an astrological wheel and rulers of opposing houses — for example, the first and the seventh (that’s you, Aries and Libras) or the fifth and the eleventh (Leo and Aquarius) — sister signs share the same quality (also known as quadruplicities):
Cardinal: These signs are the visionary thinkers of the zodiac, excelling at brainstorming and initiating, but they struggle with follow-through. They include Aries (fire), Cancer (water), Libra (air), and Capricorn (earth).
Mutable: These signs are the most flexible of the zodiac, but they can also be indecisive and whimsical. They include Gemini (air), Virgo (earth), Sagittarius (fire), and Pisces (water).
Revised: These signs resist change, for better (let’s say, being open to commitment in a long-term relationship) or worse (refusing to switch career paths, even if it’s detrimental to their health). They include Taurus (earth), Leo (fire), Scorpio (water), and Aquarius (air).
And you likely already know that there are four elements: Fire, Earth, Air, and Water. Well, they’re also categorized as dualities. Fire and Air are the “active” elements, which are more assertive, energetic, and action-oriented, while Earth and Water are “receptive,” meaning they generally prefer to connect with their emotions and intuition before taking action. Sister signs always belong to the same duality.

Aries and Libra
Polar opposites: Aries, the initiating fire sign and the ruler of the First House of Self, confronts Libra, the initiating air sign and ruler of the Seventh House of Partnership. Although both are proactive, Aries is influenced by Mars, the planet of action and aggression, while Libra is primarily a peacemaker, influenced by Venus, the planet of love. Aries will literally challenge people to fight with them for amusement, while Libra will avoid conflict at any cost, sometimes resorting to passive-aggression or becoming unwell.
Perfect pair: As initiating cardinal signs, these two are equally enthusiastic about initiating large-scale projects. Impulsive and fiery Aries can encourage indecisive and airy Libra to make decisions more swiftly and confidently. In return, Libra can help tone down Aries’ confrontational approach, teaching them the power of diplomacy and using kindness to deal with conflicts, which can often be just as effective, if not more, than an aggressive approach.
Taurus and Scorpio
Polar opposites: Taurus, the stable earth sign and ruler of the Second House of Money, opposes Scorpio, the stable water sign and ruler of the Eighth House of Sex and Death. Governed by pleasure-seeking Venus, individuals born under Taurus are among the least conflict-driven signs, second only to Libra. They prefer to relax, appreciate beautiful art and food, and take life easy.
Meanwhile, Scorpio, jointly governed by assertive Mars and metamorphic Pluto, is fervent about everything, desiring to exist in their ultimate existence in a more audacious, proactive manner. As (strangely) soundless as they may outwardly seem, Scorpios have absolutely no composure.
Impeccable duo: Taureans are often referred to as the most inflexible sign of the zodiac, but in reality, all of the fixed signs possess this trait. Both the Bull and the Scorpion are inclined to take a firm stance and refuse to yield. This is why they are a perfect match for any kind of long-term relationship, whether it be romantic, platonic, or professional. They both have a deep commitment to making things work and share a mutual understanding of intensity. (Both are highly sensuous as well, so if the bond is based on love or sex, expect a lot of passion.) Taurus can assist Scorpio in embracing a more peaceful and grounded approach to life, while Scorpio can help Taurus become more comfortable delving into the depths of emotion and passion.
Gemini and Sagittarius
Complete opposites: Gemini, the adaptable air sign and ruler of the Third House of Communication, is situated opposite to Sagittarius, the flexible fire sign and ruler of the Ninth House of Higher Learning and Adventure. Governed by the messenger Mercury, Gemini constantly absorbs and shares information in a curious and often light-hearted manner. Think of the Twins as the talkative, wide-eyed children of the zodiac; they don’t take themselves too seriously. On the other hand, Sagittarius is ruled by expansive Jupiter and possesses an insatiable thirst for knowledge, often coming across as opinionated and know-it-all. Unfiltered and passionate, they have strong beliefs and opinions.
Impeccable duo: Despite expressing themselves and functioning in social settings differently, both Gemini and Sagittarius have a hunger for knowledge, connection, and eye-opening experiences. They are the two most adventurous signs in the zodiac and would thoroughly enjoy embarking on a travel adventure together, whether it be on a global or local scale. Gemini can encourage Sagittarius to consider various viewpoints, while Sagittarius can urge Gemini to adopt a deeper and more philosophical perspective.
Cancer and Capricorn
Complete opposites: Cancer, the initiating water sign and ruler of the Fourth House of Home Life, opposes Capricorn, the initiating earth sign and ruler of the Tenth House of Career and Public Image. Guided by the intuitive and emotional moon, Cancer naturally nurtures others, prioritizing family, their domestic sanctuary, and a sense of inner security. On the other hand, Capricorn, ruled by the diligent taskmaster Saturn and symbolized by the Sea Goat, is determined to climb their personal mountain to achieve recognition, rewards, and respect. This doesn’t mean that they are not family-oriented, as traditional Saturn instills a love for tradition, but their primary drive is to cultivate a commendable professional reputation.
Impeccable duo: While society tends to pit home life against work life, the reality is that you are likely to thrive and achieve success in both areas when there is synergy. Cancer and Capricorn provide a clear example of how these seemingly opposing energies not only can, but must, work together.
Cancer demonstrates to Capricorn how to rejoice in the delights of domicile, purely connecting with cherished individuals, and tending to one’s innermost feelings, while Capricorn enlightens Cancer about the gratifications of gaining professional recognition and imparting a pragmatic and unwavering methodology to achieve tangible outcomes. In the end, these two possess a greater similarity than initially apparent, as they harbor a shared aspiration to construct something that endures and brings satisfaction.
Famous Example: Prince William (a Crab) and Kate Middleton (a Goat) are astrological opposites, as are Kristen Bell (a Crab) and Dax Shepard (a Goat).
Lion and Water Bearer
Polar opposites: Lion, the steadfast fiery sign and ruler of the Fifth House of Romance and Self-Expression, sits across from Water Bearer, the unchanging airy sign and ruler of the Eleventh House of Networking and Long-Term Desires. Governed by the radiant sun, self-assured Lion desires to be in the spotlight, have a good time, dance, possess and utilize their fierce roar, flirt, fall deeply in love, engage in lots of passionate sexual encounters… essentially behave like an ’80s music icon. However, forward-thinking, team-oriented Water Bearer, whose modern ruler is rebellious Uranus and whose traditional ruler was taskmaster Saturn, is an intellectual idealist focused on what benefits the collective as opposed to the individual. Free-spirited, logical, and eager to challenge convention, they are most likely to seize the spotlight when they are advocating for a societal cause alongside friends or colleagues.
Perfect pair: Lion’s concentration on self and inclination to be outspoken and proud will most certainly clash with Water Bearer’s composed, stoic demeanor and dedication to the community. However, by working together, they will realize that they need each other’s abilities and perspectives. In fact, as two steadfast (also known as stubborn) signs who believe their approach is the superior one, they are far more similar than they might initially assume. Lion can teach Water Bearer how to promote and market themselves for the sake of their humanitarian campaigns, while Water Bearer can assist Lion in broadening their perspective beyond their glamorous, shimmering bubble and utilizing their roar for endeavors that benefit community causes close to their hearts.
Famous Example: Mila Kunis (a Lion) and Ashton Kutcher (a Water Bearer) are on opposing sides of the astrological chart.
Maiden and Fish
Polar opposites: Maiden, the adaptable earth sign and ruler of the Sixth House of Health and Daily Routine, opposes Fish, the adaptable water sign and ruler of the Twelfth House of Spirituality. Governed by investigative Mercury, practical, analytical Maiden prioritizes facts, figures, checklists, spreadsheets, and minutiae that come with detailed references. And they find great joy in utilizing their information-gathering skills to be of assistance to their loved ones or colleagues. In contrast, Fish is ruled by Neptune, the planet of dreams that tends to obscure rational thought. Deeply sensitive and slightly intuitive, they are predisposed to letting their emotions, intuition, and imagination take precedence over logic.
Perfect pair: Taking care of the details of daily life and one’s health and well-being may sound unstimulating, but Virgos understand that there can be enchantment in maintaining organization.
Arranging your ducks in a line can generate room for recreation and verse, and that’s precisely what Virgo can bestow upon Pisces. And Pisces can assist Virgo in moving away from overthinking and embracing their emotions and essence, gaining confidence to immerse themselves in the profound depths of their most intricate, bewildering emotions. In the end, both the Fish and the Maiden might recognize that they are essentially identical as empathetic individuals who aspire to utilize their talents in mending others.
