Kordylewski cloud

Diagram showing the Lagrangian points of the Earth–Moon system. Kordylewski clouds exist in the regions of L4 and L5.

Kordylewski clouds, also named ghost moons, are concentrations of dust that exist at the L4 and L5 Lagrangian points of the Earth–Moon system.[1][2][3][4] They were first reported by Polish astronomer Kazimierz Kordylewski in the 1960s, and confirmed to exist by the Royal Astronomical Society in October 2018.[2][3][4]
