We have different ways of categorizing the Zodiac signs, houses, planets, and other bodies, and one of them is by element. Astrology has 4 elements: fire, earth, air, and water. But what does it mean if you're missing one of those elements in your natal chart?
The Elements in Astrology
Astrology has 4 elements, which each have 3 Zodiac signs. They are:
Fire: Aries, Leo, Sagittarius
Earth: Taurus, Virgo, Capricorn
Air: Gemini, Libra, Aquarius
Water: Cancer, Scorpio, Pisces
Each element has its own base energy. The fire signs are active and take action; the earth signs are practical and responsible; the air signs are intellectual and social; and the water signs are emotional and intuitive.
If none of your planets fall in the signs of one element, that element is missing in your natal chart. This is often seen if you have a stellium (3+ planets in one Zodiac sign). If only one planet is located in the signs of an element, that's called a singleton (and the energy of the element gets funneled into it hard).
What Missing the Elements Mean in Astrology
Missing fire: You may struggle with taking initiative, being assertive, focusing on the positives, or taking chances on yourself. You may have difficulty having the energy you need for what you want in life.
Missing earth: You may struggle with being stable, secure, reliable, or responsible. You may not seem very practical, and may need to work on trying to be more grounded and more connected to the physical.
Missing air: You may struggle with using your mind, with being curious, or with being sociable. You may have to work harder at expressing yourself, feeling heard, or connecting with others mentally.
Missing water: You may struggle with emotional expression, understand yourself emotionally, or connecting with others emotionally. You may need to work on allowing yourself to be emotional.
What to Do When You're Missing an Element
There is some belief that if you have the missing element represented on one of your angles, that pumps up the angle and you get to focus the energy of that element there. There are 4 angles in astrology, and each correspond to one of the main pillars of your life:
Ascendant = the self (associated with 1st house)
Imum Coeli = home/family (associated with 4th house)
Descendant = others/relationships (associated with 7th house)
Midheaven = career/goals (associated with 10th house)
So, say you have no planets in any of the air signs (Gemini, Libra, Aquarius), but you do have your Descendant in Aquarius. That would channel air energy in your dealings with others and relationships (so you'd be super sociable, attract tons of air people, and need lots of mental connection in relationships).
But what about if you don't even have that? That doesn't mean you're missing the element completely, because you still have the planets. So, if you're missing fire, look to your natal Mars, who is the fiery planet. Look to the sign and house location your natal Mars, and that's where you'll likely find fire energy is focused for you.
If you're missing earth, look to your natal Saturn, whoo is super earth. Look to the sign and house location of your natal Saturn, and there's where you'll likely find earth energy is focused for you.
If you're missing air, look to your natal Mercury, the planet of the mind. Look to the sign and house location of your natal Mercury, and that's where you'll likely find air energy is focused for you.
If you're missing water, look to your natal Moon, the watery emotional planet. Look to the sign and house location of your natal Moon, and that's where you'll likely find water energy is focused for you.
