3I/ATLAS is only the third interstellar object detected visiting our solar system, after 1I’Oumuamua in 2017 and 2I/Borisov in 2019. (The 3I in the newfound object's name stands for "third ...

For only the third time, astronomers have found something passing through our solar system that came from outside the solar system. This interstellar object, known as 3I/ATLAS, is still pretty far ...

In comparison, the first known interstellar visitor, 1I/'Oumuamua, had an eccentricity of about 1.2, and 2I/Borisov came in at 3.6. 3I/ATLAS massively outpaces both.

3I/ATLAS is just the third recorded interstellar object to enter the solar system. However, the scientific consensus is that it's likely a comet.
