Researchers are confident that objects similar to Oumuamua often arrive in our solar system. Approximately seven different objects can fly by each year, reports Yahoo News.
The cigar-shaped space rock `Oumuamua was the first known interstellar object to visit our solar system, and made headlines around the world as it passed Earth in 2017.
The second interstellar object spotted in our solar system was 2I/Borisov, spotted by Crimean amateur astronomer Gennadiy Borisov in 2019.
Experts note that they were not able to study these objects well enough, because they were noticed already when they left the solar system.

Professor Avi Loeb even suggested that Oumuamua might be some kind of a̳l̳i̳e̳n̳ technology or even an a̳l̳i̳e̳n̳ spaceship.
Harvard scientist disagrees with most of his colleagues, who perceive the object as no more than an ordinary stone, and argues that the strange shape and the way in which the object was moving all the time of the observation indicate its a̳l̳i̳e̳n̳ origin. He also added that it could be debris that the a̳l̳i̳e̳n̳s threw into outer space.
That is why experts decided to check how many interstellar objects can enter the solar system in a year. According to preliminary results, their number may reach seven.
In the future, in order to capture the interstellar objects in time, or at least some of them, Vera Rubin’s observatory will be involved. If objects are discovered before they leave the solar system, then spaceships may even be sent to study them.
