The interplanetary aspects

From Astrology In Depth

The Conjunction - a 0 degree angle between planets or points, give or take 10 degrees (on either side). This aspect shows the fusion of two types of energies together. These planets embrace each other, and seek to work together.

The Square - a 90 degree angle between planets, give or take 10 degrees (on either side). This aspect reflects an irritated, energized (sometimes too much so) influence of two types of energies that take up the fight as they differ in focal quality and direction of their desired expression.

The Opposition - a 180 degree angle between planets, give or take 10 degrees (on either side). This aspect reflects a deep chasm between the planets involved, where the energies try to push in opposite directions, always leaving something to be desired. The result is a whole lot of stress which may be taken out inappropriately (usually in secret).

The Trine - a 120 degree angle between planets, give or take 8 degrees (on either side). This aspect reflects acceptance, much ease and taking pleasure in the expression of the planets involved. There is no stress between them, and so this often does not produce the same spectacular results of the other aspects.

Minor aspects

The Sextile - a 60 degree angle between planets, give or take 6 degrees (on either side). This aspect is a somewhat positive, minor influence, however as planets tend to share a passive/active quality through a different element, they do not naturally attract to working together, and as such may require conscious effort.
