The Aspects
Here we want to take a look at WHEN a particular
angular separation is considered an "aspect," and thus,
the subject here is one of "orbs." We know when an
angular separation is exact, so that is no problem. In
other words, an exact trine aspect is 120 degrees, no
more and no less. At that moment, there are no orbs.
But the question here is: as we approach an aspect, at
what point can we say that we are within reach or
influence—within the “orb effect” of that aspect? When
does it affect us? As you might guess, astrologers agree
to disagree on when or where this exact point is.
Moreover, astrologers use different orbs, depending on
which planet they are considering, as well as which
aspect they are considering, so it can get a little
complicated. In this lesson, I will stay away from the
extremes and just present the orbs most commonly
used by astrologers. You are free to use any orbs you
wish, of course.
