Interstellar Comet 3I/ATLAS Nears Perihelion with Surprising Activity and Earth-Defense Potential

Interstellar comet 3I/ATLAS is passing perihelion and has been observed by amateur astronomers and space agencies, showing typical comet features like a coma and dust tail. Despite hype and speculation, it appears to be a normal comet from beyond our solar system, with ongoing observations expected to continue into November and December. The discovery highlights our improving ability to detect interstellar objects, with future telescopes likely to find more such visitors.
