In a new paper published on Monthly Notices of the Royal Astronomical Society scientists explain that they have confirmed the presence of two dust clouds orbiting the Earth at the same distance as our Moon. The discovery is the confirmation of a work dating back to decades in the early '60s, when the clouds were first discovered.
The presence of dust clouds has been extremely difficult to prove because they are so weak. They are collections of extremely tiny particles spread over an enormous area that dwarfs even the Earth itself, but they are definitely there.
These "moons", as some call them, obviously are not actually moons as you normally would think of them. They are just huge and thin clouds of dust trapped in the Earth's orbit. They are many times the size of the Earth itself but you can not see them with the naked eye because not enough light bounces off the tiny particles and finds its way to our planet.
The great puffs of space dust were called "Kordylewski clouds", which is a sign to the astronomer Kazimierz Kordylewski, the first person who claimed to have spotted them in 1
"The clouds of Kordylewski are two of the most difficult objects to find and, although they are closer to the Land of the Moon, they are largely neglected by astronomy researchers" Judit Slíz-Balogh, coauthor of the new study, declared in a note. "It is curious to confirm that our planet has dusty pseudo-satellites in orbit next to our lunar neighbor."
The existence of dust clouds does not mean much to you and me, but it sheds light on the dynamics of the Earth's orbit. The points where the dust is trapped are known as Larange points and scientists believe that places like these could be the most ideal spots for locating space stations or satellites for long-term use.
