5 months ago3I/ATLAS: Interstellar comet comes closest to Earth DW 12/19/2025
In the early morning hours of Friday, December 19, you could spot the visitor from another solar system in the sky with a serious telescope, that is. Comet 3I/ATLAS flew by Earth at a distance of 270 million kilometers (168 million miles). That was its closest approach to our planet. From here, the comet will continue its journey and pass by Jupiter in early 2026 before crossing the orbits of Saturn, Uranus and Neptune by 2028 and then leaving our solar system.
