Recently, researchers have detected Oumuamua a mysterious object moving in the space and later journey and its origin study published in science journal Nature Astronomy.
The object Oumuamua considered as first identified interstellar object revolving in the solar system. Previously found in last September and considered it as comet as cigar shaped object width of about 30 meters and a length of 200 meters in the past and again concluded as asteroid.
Wes Fraser, from Queen’s University Belfast, and colleagues who have been analyzing the brightness measurement of the object. And found that unlike most bodies in the Solar System, Oumuamua does not spin periodically. Instead, it tumbles, or spins chaotically, through space and could have been this way for many billions of years.
Scientists have long suggested that the asteroid has been traveling through the Milky Way for millions of years before it entered the Solar System.
One might require the Large Synoptic Survey Telescope (LSST), an observatory with an unprecedentedly panoramic view that should begin scouring the skies in the early 2020s. But the discovery of ‘Oumuamua with a less-sensitive observatory called Pan-STARRS implies these objects are much more common.
Oumuamua collided with another before and this fiercely tossed it out into the interstellar space.
“Assuming a body that responds to non-principal axis rotation in a similar manner to Solar System asteroids and comets. The timescale to damp 1I/’Oumuamua’s tumbling is at least one billion years,” the researchers wrote in their study. 1I/’Oumuamua probably set tumbling within its parent planetary system and remain tumbling well after it left ours.”
In spite of the fact that the correct explanation behind the movement isn’t clear. Scientists believe that Oumuamua collided with another before and this fiercely tossed it out into the interstellar space.
Scientists, in any case, can’t get a high-determination picture of the question see the sort of hole that it has. Which can reveal insight into the crash that made Oumuamua begin tumbling.
“It was most likely sent tumbling by an impact with another planetesimal in its system. Before it was ejected into interstellar space,” Fraser said.
“This space cucumber had origins around another star, has had a violent past, and tumbles chaotically because of it.”
The torque as of now reshaped the object over the time it has spun fiercely through space. When it splashes up the majority of the energy, will float delicately through space.
