These asteroids can shine some more light onto the connection you have with certain special people in your life. You can use these in your Synastry comparison for better understanding. has a section where you can enter the numbers of the asteroids you want to check.
Conjunctions are the strongest aspect, other aspects are rather weak for the interpretation of asteroids.

These asteroids must touch an inner planet in order to consider it’s powers effective and more pronounced. I’d suggest a tight orb between 0-3 degrees. (Asteroids don’t carry as much “power” as inner planets do, that’s why the orbs must be tight to trigger a reaction from the two.)
