What Are Sister Signs In Astrology?

There's something to be said about celestial connections. Whether you're looking for love compatibility between zodiac signs or using psychological astrology to help you grow, how our stars align plays a significant role when making connections. According to Nautilus, the science of astrology is rooted in the idea that the planets and stars affect the way we behave in our day-to-day lives. You may be familiar with the changes surrounding every major astronomical shift such as mercury retrograde, new moons, etc.


Allow us to introduce you to a new concept of astrological connection: sister signs. Per Astrotalk, sister signs refer to astrological signs that are opposite each other on the astrological wheel. While it's assumed that opposite signs are inherently different, sister signs share a cosmic connection that's unique to each pair. What one sign lacks, the other holds in abundance — creating a perfect dynamic for improvement and change. We've got all the latest information on identifying your sister sign, what it can mean for you, and any fun facts about your astrological chart.

Finding your sister sign

In order to find your sister sign, you have to identify your sun, moon, and rising signs. Having a holistic understanding of your astrological chart will help you better align with your sister sign. According to Shape, use an astrological wheel to locate the sign facing 180 degrees opposite of yours (or six signs away). For example, Aries and Libra, Leo and Aquarius, Taurus and Scorpio, and so on. Make sure to identify the sister sign to your sun, moon, and rising, as all of these astrological placements are essential to who you are.


Depending on your astrological element, different sister signs can have their own unique qualities. Big-picture thinkers — like Aries, Cancer, Libra, and Capricorn — are called cardinal signs, while more adaptable signs are referred to as mutable (Gemini, Virgo, Sagittarius, and Pisces). For fixed signs, like Taurus, Leo, Scorpio, and Aquarius, qualities are described as willing to 'dig their heels in,' doing everything they can to get what they want. Once you identify your chart and sister sign(s), these qualities may sound familiar.

What it means to have a sister sign

Having a sister sign means sharing similarities and differences. For example, Taurus and Scorpio have polar opposite qualities, such as Tauruses seeking pleasure over productivity and vice versa. Scorpios lean more towards taking charge, while Tauruses prefer to be a part of the pack. On the other hand, Taurus and Scorpio signs are both fiercely stubborn and set in their ways, leaving little to no space for other people's opinions. Where Scorpios worry, Tauruses are reassured. Where Tauruses may be shy, Scorpios can help them feel more confident.


In addition to what the astrological wheel tells us, the elements of each sister sign can tell us more about who we are and how other personalities mix with ours. Earth and water signs are typically more reserved and receptive than fire and air signs, who prefer to lead and remain active (just like their elements!). Sister signs offer a duality that can't always be found in our daily lives.
