Interstellar Comet 3I/ATLAS is Making Its Way Closer to Earth—And New Research Suggests It Probably Isn’t Alone

Interstellar Comet 3I/ATLAS Approaches Earth

Scientists suggest that 3I/ATLAS, one of the rarest comets ever seen, is likely not alone and that more interstellar objects may soon be on the way.

Astronomers have detected 3I/ATLAS, the third confirmed interstellar object in our planetary neighborhood, and expect to reveal more such visits as common occurrences thanks to advanced detection methods.

As 3I/ATLAS journeys past Mars and makes its closest approach to Earth, it will be obscured from view as it travels behind the Sun.

Such discoveries are likely, even though 3I/ATLAS is only the third confirmed interstellar object astronomers have detected in our planetary neighborhood.

Author's summary: Comet 3I/ATLAS approaches Earth, possibly with others to follow.
