A stellium refers to when someone has at least 3 planets in 1 sign or house in their natal/birth chart.

　　There is some disagreement and debate over if 3 or 4 planets are required to be considered a stellium, but don’t get hung up on the details. For our purposes today, we’re going to stick with the rule of 3.

　　Depending on the astrologer, each will take a slightly different stance on stelliums, but there are across the board truths that make a stellium something to be examined seriously in a birth chart. When a stellium shows up, think about the phrase ‘with great power comes great responsibility.’

　　What does this mean as far as how it affects our minds and lives? Stelliums bring a lot of energy and intensity to the subject of that house or the nature of that sign in someone’s life. It means someone will need to work harder to become balanced, but it also means they can really concentrate their energy to get great things accomplished in the area where the stellium occurs.

　　

How A Stellium in a Sign Affects You

Often, people with a bunch of planets in a single sign will end up really feeling the characteristics of that sign in their psyche. I have my Moon, Mercury, and Venus in Leo, which means the traits of a Leo overshadow my emotions (Moon), my communication (Mercury), and my Venus (love).

　　This means I have a lot of potential arrogance working against me that I have to be aware of in order to have good relationships. All that fire energy will compel me to be the center of attention and a leader, and I’m often attracted to people who have a lot of charisma and confidence. All of this is true and if I tried to deny it, I would be very out of touch with my core nature. However, if I use my heightened Leo energy for good, it can be a gift.

　　Similarly, my brother has a stellium with his Sun, Mars, and Mercury in Leo. His core personality, his communication, and his passion will all be fiery as a result. He has a loud voice, easily lands leadership positions, and communicates confidently. His passion comes across clearly without inhibitions from that Mars influence as well. Both he and I tend to work all the time, which is a typical imbalance seen when a stellium occurs. However, it also allows us to accomplish a lot and get farther because we are so focused.

　　Another friend of mine who has his Sun, Moon, Mercury, Venus, and Pluto in Scorpio is the perfect example of how someone with a stellium operates. He’s so focused on deep emotional issues that he ignores everything else. He’s a true artist, channelling all of his mind, body, and spirit into meaningful creations. He puts all of his life energy into his art. His mind is extremely deep and he is prone to having only intense conversations with people. He’s able to accomplish a lot with all that energy, but may forget to tie his shoes!

　　

How A Stellium in A House Affects You

In order to find out if you or someone else has a stellium in a house in their chart, you’ll need to know the exact time, date, and location of birth. Essentially, a stellium in a single house means you’ll be very challenged in the area that house rules where all those planets show up. You may have a lot of learning experiences related to that area of your life. Some astrologers believe it’s because you have karma in that area to work through.

　　Stelliums can leave other houses empty. Some astrologers believe that means that area is not a place where you need to focus on because you likely don’t have karma in that area to work on in this lifetime.

　　If someone seems to go through very similar patterns in the same areas in their life that look like the same lessons with slightly different characters and contexts, you can safely bet there’s a stellium in the corresponding house.

　　

Concluding Thoughts…

Stelliums are a great way to understand people who are really good at certain things and really bad at everything else. They also can help explain why some people breeze through certain areas of their life while in others, they keep hitting their head against a wall. It really helps me accept other people and the life lessons they are going through without judgement, as well as to do the same for myself.

　　Understanding the influences of a stellium is something that can truly shift your perception of reality from confusion to empowered. It can help you unpack the seemingly confusing behaviours of people who are obsessive about things or keep experiencing similar situations in their lives.
