More than a year after the appearance of a fireball in Canada, scientists have returned to the nature of this object, long considered a comet because it came from the Oort cloud. According to the latest information reported on this appearance by the experts, the object would rather be made of rock and not of ice. This characteristic makes it possible to indicate that the identified object is probably an asteroid. For other observers, this discovery could further help to understand the formation of the solar system.
« This sheds light on the fact that there is dispersion and deposition of matter from all over the solar system in the Oort cloud.”Explain Karen Meech, a scientist at the Hawaii Institute of Astronomy. The object that appeared in a Canadian province on February 22, 2021 was a space rock weighing about 2 kg. It had evaporated as it entered the atmosphere. For Bill Bottkea laboratory dynamics specialist Southwest Research Institutethe discovery could also have the merit of some models according to which objects from the asteroid belt were dispersed in the Oort cloud.
Other unidentified objects
Also remember that several unidentified objects were recorded. Scientists, however, failed to draw the conclusion that they were or were not asteroids. “He was brilliant, very fast and left a luminous train behind him in the center of the atmosphere”, had described for his part Denis Vida. For several years, these countries have been considered comets. A similar case had been identified in 2016 by the teams of Karen Meech. The tail of the object was devoid of ice.
