around the world, but fortunately the community of amateur astronomers was able to continue observing the comet for the following days, detecting in their images that the nucleus of the comet had begun to fragment. Disintegration is one of the final destinations of many comets, made up of loosely cohesive blocks of material, with highly volatile content and bound by the microgravity inherent in their small size. In each approach to the Sun, its structure weakens due to the sublimation of the gases -mainly water- contained, which in turn drags solids, and to the tidal forces caused by the powerful gravity of the Sun. The most beautiful consequence of all this The process is the formation of the long tails that most comets show. During the second half of

March, different observers were able to follow how Hungary Phone Number List the fragments of comet ATLAS were separating and, in turn, disintegrating into other smaller fragments. The Hubble Space Telescope observed them in detail on April 20 and 23. And the latest studies on the arrangement and evolution of the fragments, in parallel and not as a “train of fragments”, suggest that, probably, the fragmentation happened at a great heliocentric distance and not at these moments of minimum distance from the Sun. Still, the C / 2019 Y4 (ATLAS) fragments, as well as any disintegrating comet, follow the same orbit as the original object and are only a few thousand kilometers apart. In no case do they modify their trajectory substantially and they do not represent any type of

danger, therefore their closest approach to Earth will be on May 23, 2020 at 0.78 AU from our planet, 117 million kilometers. At the beginning of May, at least the two main fragments were still being observed. It seems that they will reach perihelion on May 31, but shining far less than expected. * An astronomical unit equals the average distance between the Earth and the Sun. 150 million kilometers, approximately. Modern roses are the result of artificial crosses and improvement programs carried out since 1867, with the arrival in Europe of species from India and China, with the aim of promoting their ornamental use. The cultivated roses that existed in Europe up to that date have practically disappeared, with the exception of Rosa damascena and Rosa
