In the past decade, astronomers have witnessed three interstellar objects (ISOs) passing through the solar system. These include the enigmatic ‘Oumuamua in 2017, the interstellar comet 2I/Borisov in 2019, and 3I/ATLAS in July 2025. This latest object also appears to be a comet, based on recent observations that showed it was actively releasing water vapor as it neared the sun.
