Since the celestial bodies on the Lagrangian point can maintain a stable orbit, is it possible that the materials left over from the formation of the solar system are still wandering in these places? Scientists have previously discovered some small celestial bodies at the Lagrangian points of the sun and Mars, the sun and Neptune, and the sun and Jupiter. So, will there be objects at the five Lagrangian points between our earth and the moon? In other words, will there be some small satellites on the earth that we haven't found?
For 60 years, scientists have been studying and looking for this problem. According to the mass of the earth and the moon, scientists speculate that there may be substances at Lagrange points L4 and L5, but it is still unknown whether this substance can exist stably due to the extra gravity of the sun and the action of the solar wind. 196 1 year, Polish scientist Kazimierz Kodilevsky observed the signs of ghost dust cloud near L5, so it was called Kodilevsky cloud, but there was not much research on it later.
Recently, researchers at Roland University in Hungary began to re-examine this work. They established a mathematical model based on the gravitational interaction between the sun, the earth, the moon and the dust cloud, and found that there may be a constantly changing ghost rotating dust cloud at the L5 Lagrange point.
Does this ghost satellite exist or not? Research member Judith Barlow and others made observations through the private observatory in Knittel Demetz village, Baodao Bridge, Hungary. This telescope can measure polarized light and can find evidence of polarized light from dust clouds. After several months' unremitting efforts, they finally found the polarized scattering of solar light by the suspected dust cloud L5 for two consecutive nights.
Scientists also pointed out that although they have carefully ruled out any other potential sources of polarized light, such as artificial signs such as telescopes, clouds or aircraft wakes, this so-called ghost satellite may still be only a short-lived phenomenon, because any dust is easily hooked away by the gravity of other celestial bodies or dispersed by the solar wind, and no evidence of these dust observed by other telescopes has been found. In 1990s, Japan sent Hiten detectors to L4 and L5 Lagrangian points to look for these captured particles, but found nothing.
Whether there is a ghost rotating satellite composed entirely of dust on the earth is still a mystery and has not been finally confirmed. I hope more observations can confirm this in the future. Oh, no, it should be two o'clock. Such a ghost satellite may also exist at the L4 Lagrange point of the Earth-Moon system. Actually, there is no need to go to so much trouble. According to our existing technology, we can send several satellites to these points just to study whether they will be hooked by other celestial bodies. However, what I can think of is whether the james webb telescope will collide with these possible substances in the future, because it runs at L2 Lagrange point between the sun and the earth.
Moreover, according to Wikipedia, although Cody levski Cloud is very faint and difficult to see from the earth, it can still be seen with the naked eye on very dark or transparent nights. The angular diameter is about 6 degrees, which can deviate from L4 or L5 Lagrange by 6 to 10 degrees. For reference, the diameter of the sun and the moon is only about half a degree, and this ghost satellite is actually 12 times larger than them! This statement is full of doubts, please understand it carefully.
The study was published in two papers in the Monthly Journal of the Royal Astronomical Society last month and this month.
