Many beautiful and surprising objects remain to be discovered in the mysterious outer solar system, but I don't believe that Planet Nine is one of them. Apart from any fair dealing for the purpose of private study or research, no Opinions expressed by Forbes Contributors are their own. All of the extreme KBOs that had been discovered prior to OSSOS and DES were from surveys that did not fully report their directional biases. This article is republished from The Conversation under a Creative Commons license. KBOs are leftover small bits of planetary material that were never incorporated into planets, similar to the asteroid belt.

This leads to another observation bias that has historically been ignored by many KBO surveys: KBOs in each part of the solar system can only be discovered at certain times of year. Conventional theory has it that Planet 9 —- our outer solar system’s hypothetical 9th planet —- is merely a heretofore undetected planet, likely captured by our solar system at some point over its 4.6 billion year history.
Planet 9, which NASA calls Planet X, “orbits our Sun in a highly elongated orbit far beyond Pluto.” For a fleet of tiny probes to reach it in just a decade would indeed be revolutionary.
or, by Samantha Lawler, The Conversation.
Discoveries of KBOs are also much less likely near the plane of the Milky Way galaxy, where countless stars make it difficult to find the faint, icy wanderers in telescopic images. Recently, I've contributed to Scientific American.com, Nature News, Physics World, and Yale Environment 360.com. Is There a Mysterious Planet Nine Lurking in Our Solar System Beyond Neptune?

Loeb says that the formation of primordial black holes would definitely represent new physics. So, the authors propose that a unique wide-field survey telescope, now under construction in Chile, will soon allow them to set new limits on the possibility that Planet 9 may indeed be a PBH instead of just an ordinary planet. part may be reproduced without the written permission. Searching for KBOs requires careful planning, precise calculations and meticulous followup.
VI. 1.2M posts 49.3K members Neptune's migration explains the pervasiveness of highly elliptical orbits in the Kuiper Belt, and can explain all the KBO orbits we've observed, except for a handful of KBOs on extreme orbits that always stay at least 10 AU beyond Neptune. Planet Nine is a theoretical, undiscovered giant planet in the mysterious far reaches of our solar system.

This means that the KBOs on elliptical orbits are particularly hard to discover, especially the extreme ones that always stay relatively far from the sun. Read the original article. Finding several extreme KBOs on orbits pointed in the same direction was a hint that something was going on.
Is the Elusive 'Planet Nine' Actually a Massive Ring of Debris in the Outer Solar System?
We do not guarantee individual replies due to extremely high volume of correspondence. And because we understand our biases so well, we can use computer simulations to reconstruct the true shape of the Kuiper Belt after removing these biases.
Astronomers will use the forthcoming LSST observatory in Chile to find out. KBOs do not emit their own light: These small, icy bodies only reflect light from the sun.
