Comet 3I/ATLAS is the third large interstellar visitor that we have ever discovered —- an asteroid or comet that originated outside of our solar system and was discovered passing through. Astronomers can glean information about celestial bodies by observing the light reflected off them with telescopes. When 3I/ATLAS is closest to the Earth, all the features that we are looking for will be easier to detect with our telescopes.
