0 Degrees in Astrology: Aries Energy
A planet at 0° sits at the very beginning of its sign, and in degree theory, it carries the concentrated energy of Aries regardless of which sign it occupies. This is the degree of pure potential: nothing has been built yet, but the drive to start is overwhelming.

What 0° means in degree theory
In Nikola Stojanovic's degree theory, the 0° degree corresponds to Aries, the first sign, the initiator, the spark that sets everything in motion. When any planet in your chart sits at 0° of any sign, it picks up this Aries overlay on top of the sign it actually occupies. Think of it as a double layer: the sign tells you the style, and the degree tells you the underlying drive. This is the degree of pure inception. There's enormous energy here but almost no structure, like a match just struck. Planets at 0° often indicate areas of life where the person is perpetually starting over, discovering new facets, or feeling like a beginner no matter how much experience they accumulate. The gift is fearless initiative; the challenge is sustaining momentum past the initial spark.
0° as a critical degree
The 0° degree is also a traditional critical degree for cardinal signs (Aries, Cancer, Libra, Capricorn). When a planet sits at 0° of a cardinal sign, its energy is amplified, and both the planet’s significations and the themes of the sign become louder and more urgent in the life.
In fixed and mutable signs, 0° is still significant through degree theory (it always carries Aries energy), but it doesn’t carry the additional critical degree amplification. A planet at 0° Cancer is both degree-theory Aries AND a critical degree, while a planet at 0° Taurus is degree-theory Aries but not a critical degree.
0° for each planet
Sun: Someone still discovering their identity. There's a restlessness and eagerness to define themselves, as if the life purpose is perpetually being reborn.
Moon: Emotional impulsiveness: feelings arrive fast and demand immediate expression. The instinct is to act on emotions before fully processing them.
Mercury: A mind that races ahead of its own thoughts, often speaking before fully forming ideas. Quick-starting but may lack follow-through.
Venus: Falls hard and fast, drawn to the thrill of new connections. The excitement of beginning often matters more than sustaining.
Mars: Double Aries energy makes for assertiveness that borders on aggression. Tremendous initiative and physical drive.
Jupiter: Expands through bold leaps rather than steady growth. Opportunities arrive suddenly and demand immediate action.
Saturn: Often delays the very things the native most wants to initiate. The tension between urgency and restriction defines major life lessons.
