Astronomers have opened two new natural "satellites" of Earth - RIA Novosti, 10/26/2018

MOSCOW, 26 Oct — RIA Novosti. Scientists have confirmed existence of two huge clouds from dust turning around Earth at distance approximately in 400 thousand kilometers from her surface. Their conclusions have been presented in the MNRAS.© Fotolia/sdecoret magazine Scientists have found the new satellite of Earth – an asteroid 2016 HO3 "Kordylevsky's Clouds — two most imperceptible objects in the closest vicinities of Earth. They are approximately at the same distance from her, as well as Long because of what astronomers actually never notice them. Therefore we are very glad that we managed to confirm existence of these two pseudo-satellites of our planet" — Judit Sliz-Balogh from the Budapest university tells (Hungary). In the 18th century scientists have established that small celestial bodies can move on one orbit with the planet if they are near points ahead or behind her where gravitation of the Sun and the planet is counterbalanced. Thousands of such objects, or "Trojan asteroids", have been for a long time found in orbits of Jupiter, Mars and Neptune, however until recently scientific it wasn't possible to find any such asteroid at Earth. As researchers tell, it is very heavy to look for the "Trojan" satellites of Earth as are very close to the Sun if to look at them from the surface of our planet. Today only six quasisatellites of Earth — 2016 HO3, 2010 TK7, 2003 YN107, 2004 GU9, 2001 GO2 and 2002 AA29 are known. All of them, except 2016 HO3, rotate on very unstable trajectories, and part of them has already ceased to follow Earth and has left her orbit in several years or decades after their opening. Sliz-Balogh and her colleagues have added to their assembly two more objects — so-called clouds of Kordylevsky which have managed to gain over the past half-century mythical and very disputable status. © Depositphotos/JohanSwanepoel Why the Moon not from cast iron? Scientists argue on origin of the Zemlio satellite existence their the first the Polish astronomer Kazimir Kordylevsky has started talking. Watching two "Trojan" points in Earth orbit in 1961, he has noticed that at one of them there is a big congestion of dust eclipsing light of the Sun and stars. This statement as marks out Sliz-Balogh, has been met by scepticism from scientific community as astronomers didn't believe that so large objects could keep stability in these points. Later scientists repeatedly checked Kordylevsky's calculations, but couldn't neither confirm, nor disprove them. © Illustration of RIA Novosti. Alina Polyanina Astronomy have opened a riddle of the birth of asteroid "suite" Marsavengersky astronomers have thought up a witty technique for search of traces of existence of these clouds and assessment of their sizes. They began to watch not heat and light which their particles of dust can radiate, and behind how collisions with them change polarization of the beams of the Sun passing through the "Trojan" points. In several months of observations Sliz-Balogh and her colleagues managed to find traces of the fact that sunlight has been linearly polarized by nearly a N
