Around the Earth, not only the moon turns, but also the asteroid bull trapped for a few years. There are also two clouds, the Kordylewski Clouds, recently reported by the Royal Astronomical Society.
These clouds, hard to see and locate, have been confirmed by astronomers, said RAS, gravitating around the moon at about the same distance from Earth.
They owe their name to the Polish astronomer Kazimierz Kordylewski who suggested their existence in 2001.
These are very thin clouds. About their existence, they have just published two articles in the Monthly Notices of the Royal Astronomical Society, Hungarian astronomers. These are two semi-stable points about 400,000 kilometers from the Earth.
In comparison, the Moon has an average distance of 385,000 km.
And although they should still study more, to confirm or deny the discovery, the clouds can be found at two points of the Earth-Moon system, the Lagrange points, which have a gravitational stability. Dust and objects at these points tend not to move either towards the planet or away from it. They advance or retreat from the lunar orbit.
Two of these points, 4 and 5, form an equilateral triangle with the Earth and the Moon and move with the planet as the satellite moves.
L4 and L5, however, are affected by solar gravity. In spite of this, it is advisable to concentrate the interplanetary dust at least for a good moment.
Kordylewski observed clumps of dust in Layer 5 in 1961 and several reports have verified, but they are in any case very tenuous and difficult to detect.
Earlier this year, the Hungarian group led by Gábor Horváth of Eötvös Loránd University modeled clouds to assess their formation and detection.
By polarization, they managed to observe them from a private observatory located in Slíz-Balogh (Badacsonytördemic).
