The spacecraft's trajectory was affected by the mascon beneath the lunar surface.
Mascon is a portmanteau formed from "mass" (from Latin "massa", meaning a quantity of matter) and "concentration" (from Latin "concentrare", meaning to bring together). The term refers to a region in space where there is a concentration of mass, particularly in the context of celestial bodies.
Think of 'mass' as a quantity of matter and 'concentration' as bringing things together — a mascon is a place where mass is concentrated.
