How many moons has Earth?
This is an issue that one could find when undergoing a scientific test in any primary school in the world. The correct answer yesterday is now the wrong answer today. Although Luna remains the only moon we can see when we look up to a clear sky, he is not alone – and it is not long. Andrew Fazekas of National Geographic provides the details.
"The moon of the Earth may not be alone. After more than half a century of speculation and controversy, Hungarian astronomers and physicists claim to have finally confirmed the existence of two "moons" orbiting the Earth, entirely composed of dust. "
Well before the official discovery, the researchers deduced the existence of these moons. It was not until 1961 that a Polish astronomer by the name of Kazimierz Kordylewski was able to obtain a questionable overview. The article continues.
"The clouds in Kordylewski are two of the most difficult objects to find. Although they are as close to Earth as the Moon, they are largely ignored by astronomical researchers, "says study co-author Judit Slíz-Balogh, astronomer at Eötvös Loránd University. in Hungary. . "It's intriguing to confirm that our planet has dusty pseudo-satellites in orbit alongside our lunar neighbor."
Each moon of clouds is about nine times the width of the earth. Although the moons are extremely large, the individual particles are estimated to be one millionth of a meter in diameter. This makes the training rather difficult to see, made visible only by special filters.
The gravitational attraction of two massive objects such as the Earth and the Sun is offset by the centripetal force of these orbits. These points of balance are called Lagrange points. Generations of astronomers have suspected that moons might be hiding at some of these points.

In 1950, Kordylewski was looking for strong moons in L4 and L5. It was at that time that he detected for the first time clues of orbiting dust clouds. Clouds are unstable and constantly change material. Like the human body, they remain constant while evolving.
The most curious minds among us collectively reflect on deep space, other star systems, and life elsewhere in the galaxy. We are looking at space operas like Star Trek and imagine the lives and loves of people living beyond the simple boundaries of our one planet.
Yet discoveries such as the two hidden moons of dust remind us of all that we still have to learn in our own stellar neighborhood. Pluto is a planet and it is not a planet. There are nagging speculations on the planet that have not been included in the science books you used when you were a child, tentatively named Planet X, according to CNN.
Now, the Earth has three moons. As we wait patiently to get up and distance ourselves, there is still a lot to see and learn where we are.
