Natural alien objects, including comets and asteroids from other star systems, have been discovered passing through our solar system. The first interstellar visitor, 1I/Oumuamua, was detected in 2017, moving too rapidly to be captured by the sun's gravity. It was followed by 2I/Borisov, a comet with a similar composition but an interstellar trajectory. The latest find, 3I/ATLAS, is moving at an incredible speed, indicating that larger interstellar objects frequently traverse the inner solar system. These discoveries highlight the regularity and challenge of detecting such transient cosmic bodies.
Three interstellar objects have been detected visiting our solar system: 1I/Oumuamua, 2I/Borisov, and 3I/ATLAS, indicating a trend of such bodies passing through.
1I/Oumuamua, the first known interstellar visitor, moved too quickly to be captured by the sun's orbit, confirming its origin from another star.
2I/Borisov, discovered two years later, resembled familiar comets but was confirmed to be an interstellar object based on its trajectory.
The recent detection of 3I/ATLAS suggests that interstellar objects of substantial sizes frequently travel through our solar system, challenging our detection capabilities.
