By the time astronomers first saw an unusual object that had the shape of a cigar that was pbading right in front of the sun in October 2017, they could tell from its track that the it came from another star system, but they did not know exactly what it was.
Well, they know it now. A survey published Wednesday in the journal Nature shows that the interstellar guest, named Oumuamua, is not an asteroid. This is not an underdog rocket either, as claimed by some tags
Apparently, it is a small interstellar comet
Marco Micheli, an astronomer working for the European Space Agency, said that it is the only type of this object that has been found until now.
Comets are frigid and dusty objects that have been compared to dirty snowballs. They usually frame long tails when they approach the sun. However, there was no visible tail in the last remarks of Oumuamua (which means "scout" in Hawaiian). This helped various leading cosmologists to hypothesize that it was an asteroid.
The direction of Oumuamua: what happened to the gravitational forces?
Whatever the case may be, a review of the new remarks made The ground telescopes and the Hubble Space Telescope have shown something unthinkable: the direction of Oumuamua could only be clarified exclusively by the gravitational forces applied by the Sun or the planets. This would normally occur in a situation where we would normally talk about an asteroid or a space rock.
Unexpectedly, they discovered that Oumuamua was not retreating as fast as it should be under gravitational forces alone, as Micheli said in a statement. Announces
his group deduced that the surprising movement of Oumuamua must be caused by the spillage of small amounts of vaporous material from its surface. This "degbading", which is found regularly in comets, was too little visible to be influential on the direction of Oumuamua
