The discovery 🔭 has significant consequences for the understanding of those areas in the #SolarSystem behind the orbit of #Neptune. Until now, it had been assumed that although the #KuiperBelt exists there, it is “essentially empty” behind it. The discovery now suggests that this is not the case. Instead, there could be around 100 other objects that are similar in size 📏 and orbit to #2017OF https://www.heise.de/en/news/Possible-dwarf-planet-celestial-body-with-extreme-orbit-behind-Neptune-found-10397288.html
"A cousin for Pluto? New dwarf planet candidate found" by @cosmiclog / @alanboyle - A computer search of archives telescope images determined Kuiper Belt Object 2017 OF201 was actually observed many more times since discovery, now with enough info to determine its orbit and a rough size. The size estimate makes it big enough to expect it has a round planetary shape. https://cosmiclog.com/2025/05/22/a-cousin-for-pluto-new-dwarf-planet-candidate-found/ #astronomy #KuiperBelt #space
As one avenue to Planet 9 closes so another one could open, this latest object will help some theories while quash others, such is the beauty of Science.
And do not anthropomorphise Pluto, it's just a minor planet, not a sad puppy being demoted.

[Think] -the solar system ends with the 9 planets
'Beyond them lie the Kuiper Disk and the vast, spherical Oort Cloud—a cosmic deep freeze that reaches halfway to the nearest stars

They move inward They become comets

The Kuiper Belt is a region of the Solar System beyond the orbit of Neptune.

After writing a book about a #KuiperBelt object called #Pluto more than 15 years ago, I just had to write about a set of three (or maybe two?) Kuiper Belt objects that have stirred up quite a bit of curiosity. https://cosmiclog.com/2025/03/04/hubble-spots-potential-threesome-on-solar-systems-edge/ #Hubble #Space
Hubble spots potential threesome on solar system’s edge
Three bodies? No problem!
The "three-body problem" has traditionally referred to the devilishly tricky challenge of working out the trajectories of three objects orbiting each other in space. The concept has inspired a sci-fi trilogy about an alien invasion, plus a Netflix serie

I'm no dynamicist, but it sounds like the same scenario that probably resulted in the observed structure of Arrokoth. (Except they stuck together.)

❛❛ something big – often called #PlanetX – might actually be out there. And a new study by a team from #Princeton University has substantially raised the likelihood that it really exists.
The evidence comes from an apparently non-random distribution in the orientation of the #orbits of smaller outer #SolarSystem bodies known as trans-Neptunian objects or #KuiperBelt objects (KBOs). ❜❜

I really enjoyed the recent Nova five-part series Solar System: Worlds. I was delighted that more than one segment touched on specific aspects of some of the worlds that I’ve incorporated into my published (and as-yet-unpublished) stories over the years.
It got me thinking about making a list of the worlds of our solar system that I’ve set stories on or worked in one way or another. I put together the table below.
Table notes:
Earth is listed only when it plays some role other than a default setting for a story.

New #KuiperBelt objects lurk farther away than we ever thought
#SolarSystem's Kuiper Belt appears to be substantially larger than we thought.
There is, however, an outer limit to the Kuiper Belt. Right?
Until now, it was thought there was nothing beyond 48 AU (astronomical units) from the Sun, (one AU is slightly over 150 million km). It seemed there was little beyond that. That changed when NASA’s New Horizons team detected 11 new objects lurking from 60 to 80 AU.

It’s a small world.
This year I am supervising an undergraduate project student who is looking at approximations to probability distribution functions. This project was inspired by a nice paper on the arXiv by Elena Sellentin, Andrew Jaffe and Alan Heavens about the use of the Edgeworth series which I blogged about here.
It turns out that the student who picked this project hails from a place very close to Edgeworthstown in County Longford. I’ve been through there on the train going to and from Sligo, but I never thought much about the possible connection, assuming the name was a coincidence. When I met my project student yesterday for our weekly discussion, however, he told me he had looked into it and the results are very interesting.
The Edgeworth series was invented by Francis Ysidro Edgeworth (1845-1926) who was a political economist and philosopher was born in Edgeworthstown. He was the grandson of the Richard Lovell Edgeworth (1744-1817) who had no fewer than 22 children (including the novelist Maria Edgeworth) and was a founder member of the Royal Irish Academy. In a manner not untypical of the Anglo-Irish landed gentry, the Edgeworths renamed the local town from Meathas Troim (anglicized form Mostrim), c.f. Parsonstown.
There is a directly astronomical connection with the Edgeworth family too. Kenneth Edgeworth (1880-1972) was another member of the Edgeworth dynasty, `one of ‘the archetypal gentleman literary and scientific families’ who had sufficient private income to be able to pursue a diverse range of interests. Kenneth Edgeworth was an independent theoretical astronomer, best known for proposing the existence of a disc of bodies beyond the orbit of Neptune in the 1930s. Observations later confirmed the existence of this structure, often called the Kuiper belt or, especially in Irish circles, the Edgeworth-Kuiper belt.
Here’s the front page of one of his astronomical publications:
Anyway, what’s the probability that a student would randomly pick a project involving a method invented a person born just a few miles away from his family home?

Hints of a Hidden Structure Detected at The Edge of The Solar System
Out past the orbit of Neptune lies the Kuiper Belt, a vast, ring-shaped field of icy rocks. This is where Pluto resides, and Arrokoth, and countless other small objects in the cold and the dark.
These are known as Kuiper Belt objects or KBOs, and astronomers have just found hints of an unexpected rise in their density, between 70 and 90 astronomical units from the Sun.
