K Ly\/Deep Random Survey \/ SWNS<\/p>\n<p>They arrived at this number by calculating the object\u2019s trajectory to find that ATLAS\u2019s \u201cgravitational acceleration\u201d is \u201csmaller than 49 feet per day, squared,\u201d <a href=\"https:\/\/futurism.com\/space\/mysterious-object-mars-more-massive\" target=\"_blank\" rel=\"noopener nofollow\">Futurism reported.<\/a><\/p>\n<p>This was then compared to how much mass it was shedding via gases and dust particles to determine the size.<\/p>\n<p>Loeb and co. also found that the diameter of its solid-density nucleus must be larger than 3.1 miles \u2014 the upper limit<a href=\"https:\/\/science.nasa.gov\/solar-system\/comets\/3i-atlas\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\"> of current <\/a>projections that are based on observations by the Hubble Space Telescope.<\/p>\n<p>This makes it larger than \u201cthree to five orders of magnitude\u201d more massive than its predecessors, \u2018Oumuamua and 2I\/Borisov.<\/p>\n<p>\u201cThe hypothesis in question is that [31\/ATLAS] is a technological artifact, and furthermore has active intelligence. If this is the case, then two possibilities follow,\u201d Dr. Loeb (pictured) and his team wrote in a paper published on July 17. \u201cFirst, that its intentions are entirely benign and second, they are malign.\u201d Chris Michel, National Academy of Sciences, 2023<\/p>\n<p>Loeb is particularly fascinated by ATLAS\u2019 rarity, which is akin to a needle in an intergalactic haystack. \u201cGiven the limited reservoir of heavy elements, we should have discovered on the order of a hundred thousand interstellar objects on the 0.1-kilometer scale of 1I\/\u2019Oumuamua before finding 3I\/ATLAS, yet we only detected two interstellar objects previously,\u201d he exclaimed.<\/p>\n<p>Thankfully, despite rocketing toward home base, ATLAS poses no threat to Earth. However, its anomalous trajectory will bring it suspiciously close to Jupiter, Venus and Mars, with the entity passing within 1.67 million miles of Mars\u2019 orbit\u00a0around the Sun over the weekend.<\/p>\n<p>More controversially, Loeb and his team believe that the celestial passerby, which is comprised mostly of carbon dioxide, could potentially be an alien probe that <a href=\"https:\/\/nypost.com\/2025\/07\/23\/science\/rare-interstellar-object-the-size-of-manhattan-could-be-an-alien-probe-harvard-scientists\/\" target=\"_blank\" rel=\"noopener nofollow\">was sent to conduct reconnaissance on Earth<\/a> \u2014 possibly with hostile intentions.<\/p>\n<p>\u201cThe hypothesis in question is that [31\/ATLAS] is a technological artifact, and furthermore has active intelligence.
