3I/ATLAS, an interstellar comet, is approaching Earth and will make its closest approach on December 19. Despite some speculation about its origin, scientists confirm it is a natural object and poses no threat to Earth. Recent observations show it remains intact, with notable activity such as increased speed and color change, but no signs of fragmentation or artificial technology.

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.
