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, a rare comet, likely isn't alone and more interstellar objects may soon be detected.

Astronomers have observed 3I/ATLAS, one of the rarest comets ever seen, and believe that more mysterious interstellar visitors could soon be on the way.

Advanced detection methods are expected to reveal that such visits are more common than previously known, despite 3I/ATLAS being only the third confirmed interstellar object detected in our solar system.

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, thanks to advanced new detection methods.

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