(469219) Kamoʻoalewa is the official name of the Earth’s half-moon and, according to some astronomers, this semi-satellite of our blue planet is no less than a fraction of the moon.
Now the Returns to the front of the stage. First diagnosed on April 27, 2016 A study of Bon-Stars 1 asteroids in Halekala, Hawaii, which not only belongs to the Apollo asteroid family. Of course, this is one of more than 14,000 items of this type known to date No I ‘ The ellipse has a semi-large axis, which is definitely greater than 1 And distance to the sun It is less than 1.017 AU. But 2016 HO3 is mostly a satellite of the Earth, i.e. its even if it orbits the Sun. Makes it move around for a while as it orbits the earth.

Since its discovery, 2016 HO3 meanwhile has officially become (469219) Kamoʻoalewa, derived from the Hawaiian language and aCreation that represents the offspring traveling alone. We know that its size will be some ten to a hundred meters. So this is a bad glowing object The large binocular binoculars on Mount Graham in southern Arizona began to read it through a powerful telescope. It is also known as LBT in English Large binocular telescope. It has two mirrors with a diameter of 8.4 meters, placed on the same hill. Kamoʻoalewa is actually 4 million times weaker Weaker than Man can see in the dark sky. But with such large collection glasses, it is possible to concentrate enough light to read e.g. The surface of the object.
Expelled from lunar impact?
A team of astronomers, led by Ben Sharkey, a graduate student in planetary science at the University of Arizona, came to a surprising conclusion while trying to better identify its composition. This was revealed in an article published in a popular magazine .
For almost three years Ben Sharkey and his colleagues worked to prove that what he saw could not be true, and in the end it brought not only possibility but also possibilities.
Another characteristic of Kamoʻoalewa argues for lunar origin, the orbit of which is not common to other NEOs. Therefore, we will be in the presence of an ejected region on an undetermined date due to the impact on the surface of a portion of our satellite.. This is nothing unusual because we see it on earth Its appearance is undoubtedly the moon compared to the rocks .
Astronomers believe that for another 300 years Camoleva will not be a satellite of the Earth. Would have come into this orbit about 500 years ago. Still, we still have plenty of time to pay a little visit to him – .
