Do you remember Oumuamua? The name may sound rather strange, but the case is already somewhat familiar, especially for those who are familiar with galactic news. The interstellar object pbaded through our solar system at the end of last year, and still today scientists who study it continue to try to unravel it.
This is because, for the first time, Oumuamua was mistaken for an asteroid; after all, it did not seem to have a characteristic tail like comets – in fact, they are clouds of ice and dust. After a while, some studies have shown an alleged origin of the object, claiming that it could have come from a system with two suns.
Now, researchers think that Oumuamua is actually a comet. , in the end, although it could also be an asteroid; or even a mixture of both. Comets are made of rock and ice, and their structure manages to keep the water frozen – something that is only allowed in a distant place of the solar system, as in Jupiter, because they are planets quite far from the Sun. [19659002] Asteroids, for comparative purposes, are rocky objects that revolve around the belt of Mars and Jupiter. The Oumuamua, however, does not yet have a very clear distinction, transiting between these two denominations. According to Sara Russell, a professor at the Natural History Museum in London, the line separating the interstellar object from one or the other becomes increasingly blurred, since it is similar to a comet and an asteroid [19659002] But why is it so important to separate the object into such a specific definition? You see, if the researchers are in the presence of a comet, it means that Oumuamua can provide valuable information about distant planetary systems, as well as provide data on how the planets are formed.
Professor Russell adds that "comets probably formed in the outer regions of other planetary systems, so that they may be able to escape the gravity of their parent star and penetrate more easily into the world. As a result, "Oumuamua and other interstellar travelers visiting our solar system can supposedly give us some valuable clues about the nature and composition of other planetary systems. In addition, these objects can show us if our solar system is unique, or one of the many habitable systems of our galaxy. "
According to Dr. Marco Micheli and his team, who is studying the case, the interstellar object was visible to the powerful ground-based telescopes for about two and a half months after its discovery." It was last seen at the beginning of the year 2018 and is not expected to return anytime soon, as its pbadage would have been accelerated by the effect of the heat of the sun on its icy surface.In spite of this, researchers continue to observe and continue to work to extract more information about the visit of Oumuamua
