Soul Mate Astrology

There are several synastry aspects to look out for if you’re searching for your soul mate. These connections show significant attraction and compatibility between the two people, which can easily last a lifetime.


Sun-Moon contacts:

Soulmates generally have strong Sun-Moon connections in the synastry chart. The conjunction and opposition are the most powerful.

The trine and sextile are also powerful. With this aspect comes a strong feeling of support and understanding. This aspect is particularly potent when it is the woman’s Moon in aspect to the man’s Sun.

This aspect indicates a blending of the Sun person’s personality and ego with the Moon person’s supportive and emotional qualities. Together, the two of them feel like a real team, and feel stronger as a unit than they do individually.


Sun-Venus or Venus-Venus contacts:

Sun-Venus contacts are highly touted by astrologers, and for good reason!

When this aspect appears in synastry, the couple feels affection and love for one another. They love being together, socializing, and showing affection. This aspect is commonly seen in the charts of close friends and family members, as well. It shows true love and compatibility between two people.  If these contacts do not show up in synastry, Venus-Venus contacts can be substituted.

When one person’s Venus contacts another person’s Venus, your love styles are similar. You easily get along, and instinctively know how the other person wants to be loved. The conjunction and opposition are most potent, and the trine and sextile are powerful, as well.



This aspect is an indicator of passionate love. There exists a great deal of sexual and physical attraction between you. The Mars person is very attracted to the Venus person’s beauty, charm, and style, while the Venus person is attracted to the Mars person’s sexual energy, charisma, and drive. The sexual passion between you is hard to beat, and is likely to last a lifetime, especially if there are mutual aspects between Venus and Mars.

Venus-Pluto in synastry:

This is a very potent aspect in synastry. This is an indicator of karmic, transformative, obsessive love. Even if the couple separates, they will remember each other for the rest of their lives, due to the depth of passion they shared. This relationship is very intense and addictive, and, on the downside, brings out feelings of jealousy and obsession.

The conjunction is extremely powerful and transformative for both partners. An incredibly strong physical and sexual attraction exists between them. With the square and opposition, the couple may go through many power struggles and may become quite manipulative and jealous towards each other. The relationship can become quite toxic in these cases, so it is advisable to work through your issues in a clear and mature manner.

The sexile and trine are wonderful additions to a synastry chart, for they increase the intensity and passion between a couple, without all the negativity and toxicity.

This aspect is especially potent if it is mutual (i.e. Person A’s Venus aspects B’s Pluto, and B’s Venus aspects A’s Pluto).


Nodal connections:

When Nodal connections are found in synastry, the connection is powerful. Contacts to the South Node demonstrate a past-life connection that has lasted into this life. The two of you have come together to wrap up unfinished business.

There exists a haunting chemistry between the two of you that can easily last a lifetime. North Node conjunctions are equally intriguing. The planet person possesses the qualities the Nodal person needs to develop in order to grow spiritually.

There is a tremendous attraction between the couple, as well as a feeling of “going somewhere” with each other. Squares to the Nodal axis are very common in synastry, particularly from the Sun or the Moon. In this case, there is a feeling that the couple feels as though they were destined to be together, but the union is a challenging one.

This indicates a karmic relationship in which both of you need to work out past-life issues that is preventing your soul growth.


Vertex contacts:

The Vertex is like a second Descendant. When touched by transit or progressions, fated events are likely to occur. Similarly, when someone’s personal planet, Ascendant/Descendant, IC/MC, or Vertex aspects your Vertex by conjunction or opposition, a fated relationship is indicated. This is the kind of relationship that will change your life.


Saturn contacts:

Saturn in synastry is a binding force, ensuring the longevity of the relationship and a feeling responsibility to one another. Hard aspects between one person’s Saturn and another person’s important planet or point are both challenging as well as binding.

In fact, hard aspects from Saturn to another person’s Sun or Moon are very common in the synastry charts of married couples.


Conjunctions to the angles:

When one person’s inner planets, Nodes, angles, or Vertex conjunct another person’s AC/DC or IC/MC axis, a strong bond is indicated. The AC/DC is a relationship axis, while the IC/MC axis represents your private and public lives.

When another person’s planets or points conjunct any of these angles, the two of you are heading in the same direction in life. There is a feeling of “going somewhere” together. Contacts to the AC shows a strong physical attraction; contacts to the DC indicate the planet person possesses the qualities you look for in a partner.

Conjunctions to the IC indicate a nurturing, protective bond, and the two people desire to have a home and family together; Conjunctions to the MC show mutual admiration and appreciation for each others goals.
