Orbs effectively measure the strength of an aspect based on how much distance is between the planets involved. Orbs can also represent how much variance can occur between planets for those planets to be considered "in aspect". For instance, the general orb for trines and squares is typically 6 degrees. If two planets are 95 degrees apart (90 + 5) they are considered to be a square because the extra degrees fall in the range under 6 degrees. But if they were 97 degrees apart, they wouldn't be considered to be in aspect with each other. Likewise, a trine with planets 124 degrees apart is weaker than one 121 degrees aparts. The effects of the 121 degree trine would be more pronounced.
