How does the visibility window of 3I/ATLAS compare to that of a typical long-period Oort Cloud comet?
Answer
Its visibility window is swifter, representing a final, highly favorable opportunity
Unlike periodic comets like Halley's (76 years), the hyperbolic path of 3I/ATLAS dictates it will not return to our cosmic doorstep, making the December 2025 event its final chance for human visual experience.
