Our siblings are some of the most important people in our lives. Just as the moon rules the mother and the father is often seen through the sun or Saturn, the siblings have their own planetary rulership in astrology as well. Mercury, the ruler of Gemini, is associated with siblings as well as cousins and extended family members such as aunts and uncles. The third house in astrology can reveal much about our relationship with our siblings. To learn more about how your siblings show up in your life based on astrology, keep reading.
The third house represents what is familiar to us…our own little personal community. Our personal community can be anything from our siblings and extended family to our neighbors. With Mercury ruling the third house, siblings are especially important as the ruler of this house can reveal a lot about how our siblings show up in our lives. For example, if your third house is ruled by Venus, you may find that you have pleasant experiences with your siblings. If your third house is ruled by Saturn, then you may find that you are either older than your siblings (as Saturn is a marker of maturity), or there could be some form of distance between you and your siblings. Thus, it is important to consider the ruler of the third house as it can reveal a lot about your relationship with your siblings.
Planets in the Third House Represent Your Siblings
If you have planets in your third house, they represent your siblings! Here are a couple of examples of how you can identify your siblings by planet positioning in the third house.
Example One-Your third house has two planets-the moon and mars. You could have a sibling that is very emotional and caring which represents the moon energy. You could also have a sibling that is very active, competitive, and perhaps a bit bossy which represents Martian energy. It is also possible that both the lunar and Martian energy show up in just one or all of your siblings. In general though, with the moon and Mars in the 3rd house, you can expect your siblings to exhibit traits of these planets.
Example Two-You have a third house with Saturn prominently placed. Saturn’s position here could mean that you have an older sibling and/or that your sibling(s) are distant from you for some reason. Saturn in the third house can also represent a strained relationship with the siblings where it may feel like “work” dealing with your siblings and/or the relationship with the siblings is quite formal.
Planetary Aspects & Your Sibling Relationships
As with all planetary placements in astrology, it is important to consider the aspects that are made to the ruler, as well as the planets within the third house as this, can change how the energy of the third house ruler as well as the planets within the third house manifest within sibling relationships.

For example, let’s say that your third house ruler, Venus, is receiving tense energy in the form of a square with the planet Pluto. Pluto rules power, control, manipulation as well as wounds, healing, and transformation. While a healthy Venus ruling the third house can create pleasant sibling relationships, the square aspect with Pluto can result in sibling relationships that are accented with power and control issues and instances of manipulation. The tense energy between the ruler of the third house, Venus, and Pluto can also represent an opportunity to explore deep traumas experienced by the siblings that can be addressed through intense healing that can lead to a transformation in the sibling relationship. It won’t be easy due to the tense aspect between Venus, the third house ruler, and Pluto, but it is possible.
Thus, it is also important to look at planetary aspects to obtain more information about how sibling relationships manifest in your life.
