This is more than 700 times the distance between Earth and the Moon, so it is a distant but scientifically interesting flyby with no risk to our planet. [](https://science.nasa.gov/solar-system/comets/3i-atlas/)Image of 3I ATLAS taken by Dave Eagle on the 30th of November 2025. !https://files.teamup.com/10295696/attachment/01KBS7N0A4FY7DJHMV4SWKASV3/preview/image.png?hash=469f65e194a8fd144f73cbe561119149a0dcc2d291e8701d308bce65d56ff496 ## Visibility from Earth Around closest approach, 3I/ATLAS is not expected to become a naked‑eye object, as it will be about 12th Magnitude, but it can be observed and imaged with telescopes. In mid‑December 2025, it is placed in the pre‑midnight to pre‑dawn sky, near the constellation Leo, making it a target for amateur and professional observers tracking this interstellar visitor.
