The Apex planet forms the peak of a triangle shape with two other planets in some aspect patterns. It is usually a focus or outlet for the combined energy of the whole aspect configuration.

This is an aspect pattern is known by several different names: Arrowhead, Thor's Hammer, or God's Fist. It packs quite a punch with sharply focused intention, aggression or assertiveness.

An Aspect Pattern is a group of 3 or more planets, all aspected to each other, forming a geometric shape. Creates a "circuit of energy" in which the planets operate together as a unit.

A Cradle is an aspect pattern with 2 planets in opposition and 2 more in trine and sextile to the opposition planets. The overall effect indicates creativity and ability to stay positive in the face of conflict.

The Grand Cross or Grand Square is an aspect pattern formed of all square and opposition aspects. It is known for its powerful driving energy.

This aspect pattern consists of 6 planets evenly spaced around the zodiac, each 60° from the planets beside it. To get 6 planets (or even including non-physical points) in orb at the same time is very rare.

A Grand Trine is an aspect pattern, where 3 planets are in a triangle shape, each 120° apart. This figure shows free-flowing, cooperative interaction and natural ability with the planets involved.

The Grand Trine Kite starts with a 3-point Grand Trine. A fourth planet has an opposition aspect to one of the planets and sextile to the other two. It contains the natural ability of the Grand Trine, combined with the striving tension of the opposition.

A Hard Wedge aspect pattern includes 2 planets in opposition, and a third "apex" planet in semi-square aspect to one of them and sesqui-quadrate to the other. The effect is generally irritating, annoying or frustrating.

This is my name for an aspect pattern of 3 planets joined with trine and sextile aspects. It usually indicates natural ability and creative problem-solving.

A Multiple Conjunction is a kind of aspect configuration in which 3 or more planets are all in conjunction with each other. These planets are typically (though not always) in the same sign.

A Rolling Conjunction is a line-up of planets where each is conjunct the next but not necessarily within orb to conjoin the others. Yet, they all act as a unit in the chart as if they were all conjunct.

A Stellium is when there are a number of planets in the same sign or house. It indicates an unusually strong focus on the sign or house where it is located.

The T-square or T-cross is an aspect pattern in the shape of a triangle made of square and opposition aspects. It indicates difficult conflict but also dynamic and motivating energy.

The Wedge aspect pattern consists of two planets in opposition, with a third apex planet in trine aspect to one and sextile to the other. The apex planet can often provide a creative outlet for the stress of the opposition.

The Yod Aspect Pattern has 2 planet joined by a sextile and a third apex planet in a quincunx aspect to both. It can bring strong irritation and frustration, requiring flexibility and open-mindedness.

When Yod aspect pattern has a 4th planet in opposition to the Yod's apex planet, it is called a Yod Kite. This puts extra stress and significance on the apex planet.
