    Was expecting clickbait, but instead got an interesting Nitter thread about quasi-moons and the nature of asteroid hunting

      glad you enjoyed it. although if you really genuinely haven’t read anything as positive as this in a while (or more positive) then you might have some media cleanup to do. this kind of content should be the norm - and it IS, for me!

    This was a fun read. TIL about quasi moons and the first one ever found. The authors enthusiasm for space is really fun. It reminds me of how I feel about any space thing when I’m baked

    I was just reading about this. This is a type of neologism known as a Ghost Word!

    the classic example (you may have heard from Vsauce) is Dord.

    It’s funny how I would see this the very next day after learning about it! (Even though that may not be true for the rest of you.) Anyone know what THAT phenomenon is called?

      Maybe some sort of aberrant Baader-Meinhof phenomenon (frequency illusion)? Although that is usually more like, I bought a Camry and now I see them everywhere, but they were everywhere before- I just didn’t notice until I had one.

      I got it to come up on the third or fourth attempt (after the same rate limit errors your were seeing). Even then it was not the easiest to read because that social network is a horrible choice to use for a longer story/article.

      But it is an interesting read.

      Below is my transcription of the dozen+ posts by the guy (who I’ve also credited), minus all the meme gifs he included.


      Latif Nasser @latifnasser

      Last January, I noticed something peculiar in my 2yo’s bedroom that - after a year of obsessive reporting - led me to a profound cosmic revelation about what’s even possible in our universe.

      So about a year ago, I was putting my little guy to bed in his crib and I noticed a strange detail on the solar system poster up on his wall

      [Photo of a kid-friendly infographic poster of the solar system]

      Venus had a moon called Zoozve. Huh, I thought. Never heard of that.

      Put the kid to bed, went back to my room and googled “Does Venus have a moon?” First hit was from NASA: “Venus has no moons.” Weird

      Then I googled “Zoozve” and got no results, literally zero results in English. Only results were in Czech and they were about zoos. Not what I was looking for.

      I called a friend (@lizlandau) who has worked with NASA for a decade and she confirmed: Venus is completely moonless. And she had definitely never heard of Zoozve.

      This started to bug me: why make up a moon on a kids’ poster? And why call it Zoozve?! (Best guess: it was a prank and Zoozve was the illustrator’s dog’s name.)

      So I called the illustrator, a Brit named Alex Foster. (He does have a dog, but it’s named Winnie.) He didn’t know much about astronomy but he swore he didn’t make it up. He said he found it on a big list of all the moons online. I believed him, but couldn’t find the list.

      Around that time, I got a text from Liz at NASA: “Wait Latif I think I figured it out!!!”

      It wasn’t ZOOZVE, it was 2002-VE, which is an actual object near Venus. The illustrator Alex confirmed that he probably misread his own writing. Aha! 2002VE! Okay so what IS 2002VE??

      2002-VE68 (its technical designation) is a giant rock. Imagine a gray pockmarked potato the size of the Eiffel Tower. (We don’t have pics of it, but this one is similar.)

      But the weirder and harder question: is Zoozve (gonna just keep calling it Zoozve) a moon of Venus or not?

      So I tracked down the person who discovered it: Brian Skiff at Lowell Observatory in Arizona.

      He has actually discovered so many asteroids that when I talked to him, he had no idea what I was talking about, genuinely didn’t remember this one.

      He said that he found it as part of the LONEOS project, an industrial-scale asteroid scavenger hunt that Congress funded during the 90s/00s when everyone was obsessed with what would happen if one hit earth. Sometimes they discovered hundreds of asteroids in a single night.

      Once Skiff realized Zoozve wasn’t a threat, he stopped tracking it. BUT I found 2 astronomers who kept looking: Seppo Mikkola in Finland & Paul Wiegert in Canada.

      They told me that Zoozve is NOT a moon of Venus. But it’s also NOT NOT a moon of Venus. It’s both and neither. WTH?

      Turns out basically everything in our solar system orbits ONE thing. Earth orbits the Sun. The Moon orbits the Earth. Etc. If you are a body in the solar system, you hula hoop one bigger thing. That’s what you do … Except for Zoozve.

      Zoozve orbits one thing: the sun. It spends all day every day doing that. BUT Venus also has a teeny gravitational toehold on it such that it ALSO ORBITS VENUS AT THE SAME TIME.

      It’s a whole new category of thing. Something that orbits a star and a planet at once. Something that is not a moon, but also not not a moon.

      They call it … a quasi-moon.

      Astronomers had been speculating that such an object could exist for 100+ years, but this was the first time anyone saw one … not only in our solar system but in the entire universe!

      But since they found Zoozve they’ve been finding all sorts of other quasi-moons (aka co-orbital objects) all over the solar system. They ring around the sun, but then seem to do weird patterns around their closest planet

      Some (called Trojans) stay in one spot ahead of or behind the planet, like a secret service agent. Some do horseshoes: go mostly around a planet but then turn around and go back the other way. My favorites do a comma shape, just wiggling back&forth. Those are called tadpoles.

      And by the way, Earth even has at least seven different quasi moons dancing around us right now!!! The most recent one was discovered in 2023!!

      Also, quasi-moons can switch planets! We (Earth) were probably the ones who - 7,000 yrs ago - flung Zoozve over to Venus in the first place. Zoozve is going to leave Venus a few millennia from now, but no one knows where it will go next.

      Anyway, I think this is so cool because everything else on the solar system map is so regular and orderly, but not quasi-moons! It’s like we discovered a bunch of new weirdos who seem to be dancing to the beat of their own drum.

      Contrary to the posters, we don’t live in a big clockwork, we live in a dance club, and while some of us are doing the same old waltz with our same old moon, there are bodies out there do-si-do-ing their way all over the solar system.

      How inspiring is it that we are alive at a time when we are just discovering this new class of paradoxical and promiscuous rock stars like Zoozve that remind us how weird and temporary and connected everything in the universe is. And how much we still don’t know.

      One last thing. If you want to hear more about this strange object, check out the latest episode of Radiolab. Tons more there I haven’t mentioned here. radiolab.org/podcast/zoozve

      Including my detailed plan to officially rename 2002-VE68 to “ZOOZVE” to immortalize the typo and thus retroactively make the poster in my kid’s room correct! This plan falls into the category of so-crazy-it-just-might-work. And we will know the answer VERY soon. END OF THREAD.

        awesome, tysm. I found another nitter instance that was able to serve it up, and if anyone else can, I recommend viewing it for the pictures, at least for the picture of the poster itself if for no other reason.

        I hate the twitter/nitter format, plus the instance is rate-limited. So OP not only saved me a click, it told me what the writing was about.

        And this is not a movie plot. So, yes, OP, thanks for the info.

          Technically, yes, that was all you needed to know.

          But it’s still a nicely told story, and worth reading if you have a few minutes (plus the link is working now).

        Its not at any lagrange points. 2002 VE68 is a quasi-satellite in a semi stable horseshoe shaped orbit. Its trapped in a 1:1 mean-motion resonance with venus so it appears to orbit venus if youre looking at it from a venusian frame of reference but it actually orbits the sun in a highly elliptical orbit. The thing goes nearly to the earths orbit and then almost mercury’s orbit. If it were a trojan it would stay pretty much inside venus’ orbital path with a bit of wandering around the lagrange point.

      meh i can get down with you Debbie downers BUT you left out the most important part of the whole story, which suggests to me that you didn’t really give it a fair shot. or didn’t understand it.

      This is the first Quasi Moon ever discovered IN THE ENTIRE UNIVERSE. and their orbits are fucking cool.

      tiiiiiny little detail that is worth noting in a genuine good faith TLDR. you failed! poop emoji

        If OP is a debbie downer, then so are you, judging by the contents of your reply.

          I’m with you OP. If they liked the story, great. If you do a tl;dr, the nerve of calling you a “debbie downer” while whining that your tl;dr was incomplete and that you did it in bad faith. Like, what the fuck? This is lemmy and is a space community, not reddit or tumblr!
