柯迪莱夫斯基云
柯迪莱夫斯基云是可能存在于地月系统的L4和L5两个拉格朗日点，由大量尘埃聚集而成的云气。这片云气是波兰天文学家卡齐米日·柯迪莱夫斯基在1960年代最先提出的，但因为这片云气极端的模糊，因此它们是否真的存在仍然在争辩中。它们可能是瞬变的现象，因为L4和L5是不稳定平衡的点，会受到内侧行星的摄动影响。

Kordylewski cloud 柯迪莱夫斯基云
Kordylewski clouds are large concentrations of dust that may exist at the L4 and L5 Lagrangian points of the Earth–Moon system. They were first reported by Polish astronomer Kazimierz Kordylewski in the 1960s, but there is still debate as to whether they actually exist, due to their extreme faintness. They may be transient phenomena, as the L4 and L5 points are unstable, due to the perturbations of the inner planets.
