It\u2019s startling how quickly we\u2019ve moved from the first pinpoint images of this comet to what we see below, which draws on Gemini North\u2019s Multi-Object Spectrograph to show us the tight (thus far) coma of the object, the gas and dust cloud enshrouding its nucleus. Changes here as the comet nears perihelion will teach us much about the object\u2019s composition and size. Some early estimates have the cometary nucleus as large as 20 kilometers, considerably larger than both \u2018Oumuamua and 2I\/Borisov, the first two such objects detected. This is a figure that will doubtless be adjusted with continued observation.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-52009\" src=\"https:\/\/mycbh.com\/Games\/spaceperium\/wp-content\/uploads\/sites\/2\/2025\/07\/noirlab2522b.jpg\" alt=\"\" width=\"620\" height=\"775\" srcset=\"https:\/\/mycbh.com\/Games\/spaceperium\/wp-content\/uploads\/sites\/2\/2025\/07\/noirlab2522b.jpg 620w, https:\/\/www.centauri-dreams.org\/wp-content\/uploads\/2025\/07\/noirlab2522b-480x600.jpg 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 620px, 100vw\"><\/p>\n<p><strong>Image:<\/strong> Using the Gemini North telescope, astronomers have captured 3I\/ATLAS as it makes its temporary passage through our cosmic neighborhood. These observations will help scientists study the characteristics of this rare object\u2019s origin, orbit, and composition. Credit: NSF NOIRLab.<\/p>\n<p>3I\/ATLAS also shows a more eccentric orbit than its predecessors. Remember that an eccentricity of 0 means an orbit that is completely circular, while as we move from 0 to 1, the orbit becomes drawn out, to the point where an orbit with eccentricity values of 1 or above doesn\u2019t return to the Sun, but continues into interstellar space. The new comet\u2019s orbital eccentricity is 6.2, considerably higher than \u2018Oumuamua (1.2) and Borisov (3.6). Perihelion will come at the end of October at a distance of 210 million kilometers, which will place the object just inside the orbit of Mars. Amateur astronomers with a good telescope may just be able to get a glimpse of it late in 2025.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-50117\" src=\"https:\/\/mycbh.com\/Games\/spaceperium\/wp-content\/uploads\/sites\/2\/2025\/07\/tzf_img_post-2.jpg\" alt=\"\" width=\"500\" height=\"124\" srcset=\"https:\/\/mycbh.com\/Games\/spaceperium\/wp-content\/uploads\/sites\/2\/2025\/07\/tzf_img_post-2.jpg 500w, https:\/\/www.centauri-dreams.org\/wp-content\/uploads\/2023\/06\/tzf_img_post-480x119.jpg 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 500px, 100vw\"><\/p>\n<\/div>\n<p><a href=\"https:\/\/api.follow.it\/track-rss-story-click\/v3\/jGd80SoQARVuRWkdPoPfzYZ66A9StjFH\">Go to Source<\/a><br \/>\nAuthor: <\/p>\n<div>Follow Centauri Dreams \u2014 Imagining and Planning Interstellar Exploration, filter it, and define how you want to receive the news (via Email, RSS, Telegram, WhatsApp etc.)<\/div>\n<hr>\n<p>SPACEPERIUM CORPS &#038; RESEARCH CONTRIBUTORS<\/p>\n<hr>\n<p>Please comment below with research and links for fellow members to conduct further research into this area.<br \/>\nYou must be registered and signed into SPACEPERIUM BLOG in order to leave your comment and get credited!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A Better Look at 3I\/ATLAS Just a short note, prompted by the release of new imagery of the intersellar object&#8230;<\/p>\n","protected":false},"author":1,"featured_media":3061,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[6],"tags":[],"_links":{"self":[{"href":"https:\/\/mycbh.com\/Games\/spaceperium\/wp-json\/wp\/v2\/posts\/3060"}],"collection":[{"href":"https:\/\/mycbh.com\/Games\/spaceperium\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/mycbh.com\/Games\/spaceperium\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/mycbh.com\/Games\/spaceperium\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/mycbh.com\/Games\/spaceperium\/wp-json\/wp\/v2\/comments?post=3060"}],"version-history":[{"count":0,"href":"https:\/\/mycbh.com\/Games\/spaceperium\/wp-json\/wp\/v2\/posts\/3060\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/mycbh.com\/Games\/spaceperium\/wp-json\/wp\/v2\/media\/3061"}],"wp:attachment":[{"href":"https:\/\/mycbh.com\/Games\/spaceperium\/wp-json\/wp\/v2\/media?parent=3060"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mycbh.com\/Games\/spaceperium\/wp-json\/wp\/v2\/categories?post=3060"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mycbh.com\/Games\/spaceperium\/wp-json\/wp\/v2\/tags?post=3060"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
