Friendship is a beautiful—and, at times, complicated—part of the human experience. When it comes to soulmates, we tend to think of romantic love, but we can also find that closeness in our chosen family and communities, creating essential but complex relationships.

While many factors influence this type of bond, astrology can give you a deeper understanding of yourself and others, helping you forge more aligned and supportive friendships. Though there are a myriad of components to consider when looking at compatibility in astrology, below, explore the basics of sun sign synastry—and see which other sun signs might make for great friends.

The Sun Sign in Astrology

In a birth chart, the sun sign represents our life force, core identity, ego, and sense of self. It’s how we shine the brightest and feel most aligned. In short, the zodiac sign the sun is in helps serve as a guide toward our authentic self, purpose, and mission.

Synastry is the practice of comparing one individual’s astrological birth chart with another person’s chart to gain insight into their compatibility and the dynamics of their relationship. While we’ll just touch on the sun’s synastry here, the process as a whole involves examining the positions of planets, signs, and aspects in both charts to understand the potential strengths and challenges in a connection. Below, find your sun sign and your favorite friend’s, based on birth date, to uncover the synastry between you.

Sun Sign Compatibility

Aries (March 21-April 19)

Aries individuals are known for their energy, enthusiasm, and bold nature, so they often seek out friends who share their zest for life and adventure. Compatible signs for Aries include Leo and Sagittarius, as these fire signs align with Aries’ high energy and appetite for new experiences. Coming in second are air signs, Libra, Gemini, and Aquarius, who energize Aries with new ideas and direction.

On the other hand, Aries can experience friction in friendships with earth signs, Taurus, Virgo, and Capricorn, whose grounded and practical approach might clash with Aries’ spontaneity. Additionally, the watery emotional nature of Scorpio, Cancer, and Pisces can, at times, douse Aries’ fiery desire to prioritize action over feelings.

Taurus (April 20-May 20)

Tauruses value stability, loyalty, and reliability in their friendships. They are most compatible with fellow earth signs, such as Virgo and Capricorn, as these signs share their grounded and practical approach to life. Coming in second are water signs, Scorpio, Pisces, and Cancer, who can match a Taurus’ loyalty.

Air signs, like Gemini, Libra, and Aquarius, known for their detached nature, might create instability for security-loving Taurus. Additionally, the fiery and impulsive energy of Aries, Sagittarius, and Leo can also create tension, as they contrast with Taurus’ more measured and steady approach.

Gemini (May 21-June 20)

Geminis thrive on intellectual stimulation. Compatible signs include Libra and Aquarius, as these air signs appreciate a Gemini’s love of lively conversation and variety in friendships. Next on the friendship list would be Leo, Aries, and Sagittarius, who fire up Gemini’s curiosity.

While a Gemini’s communicative nature typically allows them to get along with a wide range of people, they might find challenges with earth signs, Taurus, Virgo, and Capricorn. These signs tend to prioritize consistency and stability, which threatens Gemini’s need for mental excitement. Finding common ground might require extra effort with water signs, Cancer, Pisces, and Scorpio, as well.

Cancer (June 21-July 22)

Cancers are sensitive, so they align with friends who they can give—and from whom they can receive—emotional support and understanding. They are most compatible with fellow water signs, Scorpio and Pisces, who share and understand a Cancer’s depth of feeling. After that, grounded earth signs, like Taurus, Virgo, and Capricorn, often come through for Cancer.

Cancer’s nurturing and sensitive qualities might face challenges when interacting with air signs, Gemini, Libra, and Aquarius. These signs often prioritize logic and communication over emotional depth, which can sometimes create friction with Cancer’s emotional needs. Fire signs, Aries, Sagittarius, and Leo, can also burn a little brightly for this naturally internal and self-protective sign.

Leo (July 23-August 22)
Leos value loyalty and admiration in their friendships and seek friends who appreciate their warmth and charisma. Aries and Sagittarius, fellow fire signs, are often compatible with Leo, as they share a love for adventure and excitement.

While Leos value loyalty, they might encounter challenges in friendships with earth signs, Taurus, Virgo, and Capricorn. These signs can sometimes seem reserved or practical, which might not align with Leo’s energetic desire for bold moves and forward momentum. Water signs, Scorpio, Cancer, and Pisces, can also slow Leo’s insatiable fire, requiring adjustment for the friendship to work.

Virgo (August 23-September 22)

Virgo’s analytical and practical nature make them compatible with earth signs, like Taurus and Capricorn, as these signs appreciate a Virgo’s reliability in their friendships. The emotionality of water signs, like Cancer, Scorpio, and Pisces, also balance out Virgo’s typically stoic and grounded nature.

Virgo’s analytical and practical approach to friendships can sometimes clash with the free-spirited nature of fire signs, Aries, Leo, and Sagittarius. These signs might find a Virgo to be overly critical or restrictive. Virgo can find mental alignment with air signs, such as Libra, Gemini, and Aquarius, but their inherent detachment might create internal friction for a Virgo who seeks routine and stability.

Libra (September 23-October 22)

Libras seek balance in their relationships, making them compatible with fellow air signs, Gemini and Aquarius, who share Libra’s cerebral and logical nature. Libra also tends to feel entertained and energized by the zeal of fire signs, like Aries, Sagittarius, and Leo.

Libra’s pursuit of beauty and harmony might encounter difficulties in friendships with earth signs, like Virgo and Capricorn. These signs can sometimes prioritize practicality and prudence over Libra’s indulgent need for the finer things. Taurus can appreciate Libra’s appreciation for beauty, but Libra’s airy nature might occasionally feel smothered by Taurus’ stubbornness. Water signs, Scorpio, Cancer, and Pisces, can also feel emotionally draining to Libras, who prefer to keep friendships light.

Scorpio (October 23-November 21)

Scorpios value depth and intensity in their friendships and are most compatible with fellow water signs, Cancer and Pisces, as these signs understand Scorpio’s emotional complexity. Next for Scorpio are the earth signs, Taurus, Virgo, and Capricorn, who provide structure in the emotional storm.

Scorpios might face challenges when interacting with air signs, Gemini, Libra, and Aquarius. These signs might seem emotionally detached or too surface-level for Scorpio’s liking. Fire signs, Leo, Aries, and Sagittarius, can also have the same effect. Scorpios are the secret keepers of the zodiac, and fire signs can mistakenly spill them, if not careful.

Sagittarius (November 22-December 21)

Sagittariuses are adventurous and open-minded, making them compatible with fire signs, Aries and Leo, who share their desire for exploration and new experiences. Air signs, Libra, Gemini, and Aquarius, also energize Sagittarius’ iconic, freedom-loving nature.

However, Sagittariuses might sometimes clash with the grounded and steady vibe of earth signs, Taurus, Virgo, and Capricorn. These signs might find Sagittarius’ spontaneity too unpredictable. Water signs, Scorpio, Cancer, and Pisces, can also cool down Sagittarius’ inquisitive fire, slowing them down from getting to their next escapade.

Capricorn (December 22-January 19)

Capricorns love structure and ambition in their friendships and are most compatible with earth signs, Taurus and Virgo, as they share a Capricorn’s responsible and grounded nature. Scorpio, Pisces, and Cancer are also compatible and are known for helping Capricorns connect with their emotions.

But Capricorn’s stability can pose a challenge in friendships with air signs, Libra, Gemini, and Aquarius. These signs might find Capricorn’s stoicism and work ethic to be overly rigid. Friendships with fire signs, like Leo, Sagittarius, and Aries, might lead to distress for Capricorns, as they might feel pushed to venture beyond their usual comfort zone.

Aquarius (January 20-February 18)

Aquarians value independence and intellectual connection in their friendships and are most compatible with air signs, Gemini and Libra. Fire signs, Aries, Sagittarius, and Leo, are also typically compatible and appreciate their detached friendship style.

Aquarius’ unemotional approach to life might trigger difficulties in friendships with water signs, Cancer, Scorpio, and Pisces. These signs might seek deeper emotional bonds than Aquarius is accustomed to providing. Earth signs’ rigid and, at times, traditional nature (looking at you, Taurus, Capricorn, and Virgo) might challenge Aquarius’ love for looking toward the future.

Pisces (February 19-March 20)

Pisces tend to seek out friends who understand their emotional depth. They are most compatible with fellow water signs, Cancer and Scorpio, who share Pisces’ sensitivity and fluidity. Earth signs, like Virgo, Capricorn, and Taurus, also help ground Pisces and give them direction.

Pisces might sometimes find challenges in friendships with air signs, Gemini, Libra, and Aquarius. These signs might seem detached or too analytical for Pisces’ liking. As a more fluid water sign, the fire signs can also feel jarring and challenging to keep up with for Pisces. This includes Leo, Aries, and Sagittarius.
