Original Title: TIL Ghost moons — if they really exist — are swirling clouds of dust that share Earth’s orbit, staying ahead of or behind Earth as it goes around the Sun. Officially called “Kordylewski clouds,” ghost moons were first reported in the 1960s and were only tentatively confirmed in 2018.
