「分離」（separating）的概念也適用於以下情況：當一顆運行速度較快的行星逐漸遠離一顆運行速度較慢的行星時，便稱為分離。尤其是當這顆較快的行星剛剛幾乎與較慢的行星形成精確相位，而現在兩者之間的相位度數差距開始比先前增大時，更是如此。
The concept of separating is also pertinent in the following condition. A planet is said to be separating whenever the faster planet is moving away from the slower planet, especially when it has just very nearly applied to make an exact aspect, and is now beginning to have more degrees separating it by aspect than before.
