Many suspect that this Oumuamua is actually a ship of aliens sent to spy on Earth.
In a new survey published Astrophysical journalsHarvard lecturers, Shmuel Bialy and Abraham Loeb, talked about different theories to explain the unusual behavior of Oumuamua.
Bialy and Loeb have said, when the asteroid passes through the star, releases gas that can accelerate its movement. Oumuamua did not reveal.
Two Harvard professors suspect that Oumuamua was quick to move after pushing the sunlight that struck him. Like boats specially designed with solar energy.
But there is one big question that is enough to block scientists. Bialy and Loeb are still wondering if Oumuamua is an alien ship, why send a surveillance vessel that lasts millions of years to come to the solar system?
"One possibility is an alien ship," two scientists said.
"Oumuamua can be a lightweight technology that navigates interstellar space as a small piece of advanced technology."
So far, Oumuamua is still a secret. There is no firm evidence that the asteroid is a ship for the surveillance of an alien.
