Oumuamua, the first interstellar object in the solar system, once again puzzled scientists, as it cannot be a "nitrogen iceberg"
The first interstellar "guest" of our solar system, first discovered on October 19, 2017 and named Oumuamua, is the first in history discovered "nitrogen iceberg" (as previously thought), which means that scientists again do not even have a generally accepted theory explaining the nature of this object.
Why Oumuamua is a non-nitrogen iceberg
After the interstellar object visited our solar system, scientists tried to explain the nature of the object, which swept through our system at a speed of 92,000 km / h. This incredible speed clearly indicated to astronomers that it was formed outside the system.
Moreover, when the object flew past our Sun, it acquired an acceleration that can in no way be explained by the gravitational interaction of the Sun.
And scientists have not been able to find visible traces of the presence of a propellant (for example, water vapor or various gases that come out of the gas and thus push it forward).
Scientists tried to explain these moments by the fact that, it turns out, our "space guest" most likely consists of the so-called nitrogen ice, and probably Oumuamua broke away from the planet, which resembles in its composition Pluto, located somewhere outside systems.
This theory explained both the acceleration and the impossibility of explaining the composition of the object. But astrophysicists from Harvard disagree with this opinion.
According to new calculations by scientists, in the entire universe there is not enough nitrogen ice to form an object such as Oumuamua, which is 800 meters long and 167 meters wide.
So, according to scientists, pure nitrogen in the form of ice has been found so far only on Pluto, and its content is about 0.5% of the total mass. So, as scientists assure, even if you scrape off all the nitrogen ice from the planets resembling Pluto, the collected material would still not be enough for Oumuamua.
In addition, scientists also calculated that the mass of the so-called exopluton, from which Oumuamua allegedly broke away, will weigh about 60 times more than our Sun.
The very existence of such an unimaginably large planet, even in theory, looks absurd.
Therefore, the Oumuamua object cannot be a so-called nitrogen iceberg. And it turns out that scientists again do not have any generally accepted theories explaining both the composition and the mechanism of its movement.
This means Oumuamua remains the unexplained and most mysterious object that has visited our solar system.
