Recent Kuiper Belt discoveries cast doubt a big planet exists there
The uncertainty of science: Despite predictions by some scientists that a big planet exists in the Kuiper Belt beyond Neptune, recent new discoveries of new objects there cast doubt on its existence.
If the additional big planet existed, the newly discovered objects would have shown some clustering, shepherded by its gravity.
“We find no evidence of the orbit clustering needed for the Planet Nine hypothesis in our fully independent survey,” says Cory Shankman, an astronomer at the University of Victoria in Canada and a member of the Outer Solar System Origins Survey (OSSOS), which since 2013 has found more than 800 objects out near Neptune using the Canada-France-Hawaii Telescope in Hawaii. In a paper posted to arXiv on 16 June and soon to be published in The Astronomical Journal, the OSSOS team describes eight of its most distant discoveries, including four of the type used to make the initial case for Planet Nine.
“I think it’s great work, and it’s exciting to keep finding these,” says Scott Sheppard, an astronomer at the Carnegie Institution for Science in Washington, D.C., who was among the first to suspect a large planet in the distant solar system. But he says three of the four new objects do have clustered orbits consistent with a Planet Nine. The fourth, an object called 2015 GT50, seems to skew the entire set of OSSOS worlds toward a random distribution. But that is not necessarily a knockout blow, he says. “We always expected that there would be some that don’t fit in.”
Note that I do not consider “Planet Nine” to be an accurate name for this theorized planet. Either it is #10, after Pluto, or one of a large number far more than nine, based on a new proposed and more logical planetary definition. The present definition however does not work.
Readers!
Every February I run a fund-raising drive during my birthday month. This year I celebrate my 72nd birthday, and hope and plan to continue writing and posting on Behind the Black for as long as I am able.
I hope my readers will support this effort. As I did in my November fund-raising drive, I am offering autographed copies of my books for large donations. Donate $250 and you can have a choice of the hardback of either Genesis: the Story of Apollo 8 or Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space. Donate $200 and you can get an autographed paperback copy of either.
Please consider supporting my work here at Behind the Black. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

The current definition was voted in by the Plutocracy of Giant Planets; they have a Vesta’d interest in preventing a whole Ceres of new planets trying to Charon the wealth. They will Makemake any changes difficult.
I am so very sorry. Shoot me now.
Diane: Words fail me.
Diane, imagine the next door kid from Incredibles “THAT WAS AWESOME!”
Diane, enjoyed that!
We send them to school and buy them their books, and what do we get? Punsters like Diane.
Robert,
For a long time, “Planet Ten” has been written with Roman numerals as Planet X:
https://www.youtube.com/watch?v=UU7TdtLzPrA (1-minute of “Duck Dodgers in the 24th and a Half Century”)
And besides, who made the IAU the arbiter of planets? Next thing you know, someone will say that Star Registry’s names for stars is not official — yet that company sends copies of its books of star names to the Library of Congress, so those MUST be official names. Right?
Speaking of the IAU, the version of the current rules that was actually voted on required that a planet must have “cleared its neighborhood” of other objects, or words to that effect. Even at the time, based on the number of known Near Earth Objects, Earth should have been classified as a dwarf planet.
Diane-
Great stuff!
Edward:
I have an old Scholastic Book from the mid 60’s, “The Search for Planet X.”
