The Aspects
Standard Aspect Set
Here is a set of orbs for what might be considered the
standard set of aspects, the ones most used by
astrologers. Let's go through them.
As you can see, the Sun and the Moon get the widest
orbs, and then, orbs decrease in size from the Sun to
the Moon to the planets. And, certain aspects (in
particular the conjunction and opposition) deserve wider
orbs. When any two planets are considered—such as,
for example, the Sun and Mars—use whichever orb is
widest for that pair. In this case, we would use 9
degrees for the conjunction aspect if we were looking at
the Sun and Mars. This table should be clear.
