Los Interstellar objects, Also known as ISO, has gained attention in recent years.
Since ‘Oumuamua’ was observed in 2017, they have caused a great deal of scientific excitement due to their origin outside the Solar System and their relatively close passage through our neighborhood.
Its unusual properties, such as its flat shape and non-gravitational acceleration, have generated debate, with some suggesting it could shed light on the origin of the universe, while others are more cautious.

In a recent Science article published on Arxiv, researchers Diptajyoti Mukherjee, Hy Trac, Amir Siraj and Avi Loeb note that the events of Oumuamua and 2I Borisov are not the only isolated interstellar objects (ISOs) ever detected and confirmed.
In fact, scientists point out that throughout the long history of the Solar System, other ISOs have already arrived. Here and some may be hidden in areas very close to Earth.
In their paper ‘Interstellar Encounters: Exploring the Capture of Near-Earth Orbiting Interstellar Objects’, they say they have “important implications for understanding the population of ISOs in the Solar System and their potential detection in the future”.
Through the detection of captured NEOs (Near Earth), the properties and origin of these objects and “About the formation and evolution of extraterrestrial systems and our solar system”, are described in their text.
But as it happens, only two have been identified. Here we say.
Terrestrial astronomers have already cataloged eight planets, 6,500 comets and more than 525,000 asteroids, but Oumuamua is unique.
A space object is the only celestial object known to have traveled to our solar system from a distant galaxy.
On October 19, 2017, astronomer Robert Verrick of the University of Hawaii accidentally discovered Omuamu’a. The researcher was using the Pan-STARRS telescope on the island of Maui to scan the sky for asteroids passing by Earth.
But after making additional observations, Verick and his colleagues, Marco Micheli and Karen Meech, concluded that the object’s trajectory indicated that it originated “from outside our solar system.”

“The name means ‘first discoverer of distant space’ and is pronounced ‘oh mu ah mu ah,'” Verick said.
Although it resembles a comet, it is different from anything seen in the solar system.

Comet 2I Borisov
Two years later, in 2019, the rogue comet 2I/Borisov was discovered. It is the second interstellar observer for our system, and one of the most beautiful ever observed.
Pristine, in astronomical terms, describes a comet that does not pass close enough to a star to be transformed by its heat.
2I/Borisov was discovered in 2019 by Ukrainian astrophysicist Gennady Borisov at the Marko Observatory in Crimea.
Like crocodiles, their trajectory is not sun-bound, suggesting they came to us from another system through the vacuum of deep space.
Thus, astronomers at the European Southern Observatory (ESO) suspect that a comet is more likely Never been near a star So it and the rest of the Solar System contain unbroken traces of a cloud of gas and dust that formed about 4.5 billion years ago.
It is one of a kind and makes it a gem for astronomical research.

Unlike the previous one, this item came much closer. In 2014, an asteroid half a meter wide entered Earth’s atmosphere and exploded. Off the coast of Papua Island, New Guinea, Pacific Ocean.
The combination of elements discovered is steel and titanium, a combination of metals not found in other artifacts that have impacted Earth.
It traveled 95% faster than other nearby stars in our system and its flat shape answers many questions.
The artifact examined by the aforementioned lobe did not disintegrate or destroy itself in a fireball, unlike meteorites that fall from space.
“The immediate task ahead of us is to confirm the interstellar origin of the spheres we collected from the ocean floor, demonstrating that they are not short-lived isotopes due to their long journey through interstellar space,” Loeb said.
This material is the subject of various scientific debates, as some see it as evidence of extraterrestrial life, while others consider it to be more mundane.
