Welcome to our solar system, Ammonite!
Ammonite, captured over several hours. Image credit: NAOJ, ASIAA
I imagine many of you have already heard this but just in case you might think I need to be notified by email or social media, yes, I know. And, yes, it’s very cool!
The Subaru telescope located at the Mauna Kea Observatory on Hawai’i has “found a new world within our Solar System,” affectionately (I hope) nicknamed ‘Ammonite‘ (more officially listed as ‘2023 KQ14’) by the team who spotted it. While they call it a ‘world’, it’s not a planet; technically, Ammonite is a sednoid, that is, a trans-Neptunian object with a large, semi-major axis and highly-eccentric orbit. And this one is pretty eccentric, with its perihelion between 50 and 75 AU and aphelion about 252 AU.1
I’m guessing this tiny new world (its diameter is calculated at somewhere between 220 and 380 kilometers) was dubbed Ammonite because, well, what else are you going to call a rock discovered by the FOSSIL (Formation of the Outer Solar System: An Icy Legacy) project? But I think it’s an excellent name, and will amuse myself by believing in my heart of hearts that really it’s named in honour of a certain novel. After all, NASA/JPL have already named a crater on Europa ‘Uaithne’…
Fir the geeks among us, there’s lots more info in this Nature article.
- One AU (astronomical unit) is the distance between the earth and sun ↩︎

Add another potential dwarf #planet to the list for our solar system - and this one challenges claims relating to the hypothetical existence of a large world known as #PlanetX or #Planet9 ... https://cosmiclog.com/2025/05/22/a-cousin-for-pluto-new-dwarf-planet-candidate-found/ #2017OF201 #PlanetNine #Space #DwarfPlanet

A new dwarf planet candidate has been found in the solar system. It has a large and highly eccentric orbit; its maximum distance from the sun is 1,600 times that of Earth.

🌌 Wow, another "dwarf planet" discovered!🤔 Scientists gleefully add another speck to their cosmic sticker book while everyone else struggles to care. 🚀🔍 Meanwhile, #Earthlings still struggle with basic math, but hey, at least we found another rock!🌍✨

The cold chemistry of the icy outer solar system was Mondays YorkUniverse (the @AllanICarswellObservatory radio podcast), #pluto #kuiperbelt and given todays forecast, #Toronto in Feb makes a good step in the #snow direction. We've entered bagbalm (protect) your face #weather... at least our snow is water ice and not carbon dioxide 😆🥶

Oh how I love this latest song/video from Tom Cardy, Australia’s answer to Weird Al. Somehow the song is about #Pluto being a planet and yet its also a motivational speech? And its a banger. #DwarfPlanet #Astronomy #TomCardy #MusicVideo https://youtu.be/kK0KPuH32mc

"...Pluto was one of nine planets recognised in our Solar System.
But in 2006, it was relegated to the status of dwarf planet by the International Astronomical Union..."
"...it was discoveries of Kuiper Belt Objects with masses roughly comparable to Pluto, such as Quaoar (announced in 2002), Sedna (2003) and Eris (2005), that pushed the issue to a tipping point" #Pluto #DwarfPlanet

New Horizons was the first spacecraft to explore dwarf planet Pluto up close, arriving in 2015 after a 9 year journey. You might recall images which revealed that the surface of Pluto resembled a large heart. For #spacetober prompt New Horizons I am sharing my tiny linocut of Pluto. (It’s about the size of a Canadian twonie coin).

In the arXiv, cool update on (50000) Quaoar the Transneptunian: this dwarf planet, half the size of Pluto, harbors not only a moon, Weywot, but also two rare rings, located outside the Roche limit - where rings usually accrete into satellites.
