Extremely faint patches of nebulosity, first reported by the Polish astronomer Kazimierz Kordylewski (1903-1981) in the 1950s and hypothesized to be dust that has collected at the stable Earth-Moon Lagrangian points. Although confirmed by some observers, the existence and nature of Kordylewski Clouds remains controversial. There is some evidence to suggest that they consist of fine lunar material ejected from the Moon by impacts and that they may be variable, acquiring material on the one hand and losing it, through, dynamical ejection, on the other. Dust ejected by the Clouds could eventually reach Earth and appear as sporadic meteors.
