Newton'un Güneş'in Ay'a olan perturbation kuvvetini bulmasında yardımcı olan diyagramı. (Principia Kitabından)
Güneş perturbationları için alternatif diyagram, Newton'un diyagramındaki LS vektörundeki gibi Güneş perturbationlarında da LS1 and LS2 vektörleri bulunmakta. Ay'ın Dünya'nın yörüngesindeykenki  2 konumu için çizilmiştir.
Ay Dünya'nın yörüngesindeyken solar perturbation vektörleri (oklar) birçok noktada LS ile benzerlik göstermektedir.
