Ross of Ottawa<p>It'll be interesting to watch the naming of this <a href="https://mastodon.social/tags/interstellar" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>interstellar</span></a> candidate evolve! </p><p>I'm no expert on nomenclature, but it starts out with a 'near Earth Object' tag of <a href="https://mastodon.social/tags/A11pl3Z" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>A11pl3Z</span></a> but that should change to something like 3I/2025 U1 (?) shortly if confirmed an interstellar object.</p><p>Since 1I/2017 U1 was found by a Hawaiian observatory it was given a Hawaiian name - 'Oumuamua. </p><p>This new guy was spotted by an undergrad poring over Chilean telescope data, it will presumably get a Spanish name?</p>
Ross of Ottawa<p>Digging thru the articles to see if someone mentions an eccentricity* value and I see a post that says preliminary number looks like:</p><p> e=10.4 ± 1.1!</p><p>Whew - that's probably really moving. 'Oumuamua I think was in the 1.2 region. </p><p>*An e above 1 indicates it's not carving an ellipse around our sun, but rather its hyperbolic, just barrelling thru the region.</p><p><a href="https://mastodon.social/tags/interstellar" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>interstellar</span></a> <a href="https://mastodon.social/tags/a11pl3z" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>a11pl3z</span></a></p>
simonbp<p>New paper out that I helped a little bit with: "A Demonstration of Interstellar Navigation Using New Horizons", where NSF NOIR Lab's Tod Lauer uses New Horizons images of the parallax Proxima Centauri and Wolf 359 (of Star Trek fame) to figure out the absolute position of New Horizons in near-interstellar space. </p><p>It's a very international collaboration, with participation from quite a few small-telescope observers in South America and Australia, and dedicated to the memory of a master Polynesian navigator who inspired some of the thought process. And Brian May too, because he's a friend of the mission.</p><p>My little role was in helping to analyze the pointing uncertainty in both the New Horizons and ground based data.</p><p><a href="https://arxiv.org/abs/2506.21666" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="">arxiv.org/abs/2506.21666</span><span class="invisible"></span></a></p><p><a href="https://social.linux.pizza/tags/Interstellar" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Interstellar</span></a> <a href="https://social.linux.pizza/tags/Navigation" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Navigation</span></a> <a href="https://social.linux.pizza/tags/Astrodon" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Astrodon</span></a></p>
