Earth has two extra, hidden 'moons'
First spied in the 1960s, the huge dust clouds have now been confirmed—and may affect plans for future space exploration.
Earth’s moon may not be alone. After more than half a century of speculation and controversy, Hungarian astronomers and physicists say they have finally confirmed the existence of two Earth-orbiting “moons” entirely made of dust.
As they describe in the Monthly Notices of the Royal Astronomical Society, the team managed to capture snapshots of the mysterious clouds lurking just 250,000 miles away, roughly the same distance as the moon.
Researchers previously inferred the presence of multiple natural companions to Earth, but the dust clouds weren’t actually seen until 1961, when their namesake, Polish astronomer Kazimierz Kordylewski, got a glimpse. Even then, their presence was questioned.
“The Kordylewski clouds are two of the toughest objects to find, and though they are as
