Is the fabled Planet Nine still out there ?

Could Planet Nine be lurking in the outer solar system ? Image Credit: NASA
The potential existence of an undiscovered planet in our own solar system has intrigued astronomers for years.
Nobody knows exactly where it is, how big it is or if it even exists at all, but when researchers at the California Institute of Technology revealed in 2016 that the existence of a ninth planet in our solar system was a very real possibility, the hunt for this enigmatic new world began in earnest.

Believed to be up to ten times the mass of the Earth and with an orbital period of up to 20,000 years, Planet Nine, if it exists, will be situated somewhere beyond the orbit of Neptune.

Finding it, however, is like looking for a tiny fraction of a needle in a very big haystack.

Most recently, researchers conducted a study involving six years of telescope data in an attempt to find evidence that this enigmatic world really is out there.
Captured using the Atacama Cosmology Telescope (ACT) in Chile, the observations covered 87% of the night sky visible from the Southern Hemisphere.

Despite identifying 3,000 potential candidate light sources within a relevant distance, however, the researchers were unable to conclusively confirm that any of them were planets.

While the findings may be a blow for those hoping to hear news of Planet Nine's discovery, the study does at least achieve something - it narrows down the parts of the sky that still need to be checked.

If Planet Nine really is out there, it is still possible that it will be found sometime in the near future.

I just hope that if Planet 9 is out there they will discover it within my lifetime, because I'm very curious what they're gonna call it.  My suggestions would be Persephone/Proserpina or Zagreus.

If we can't find a whole planet for so long, then I'm very skeptical we'll find the aliens ever.

My suggestions: Gangleri, or Grimnir. These are 2 nicknames for Odin. Gangleri means 'wanderer', and Grimnir means something like 'cloaked' or 'masked one'.

I'm very sceptical of a large planet nine somewhere out there in the solar system. But, it isn't impossible. It may not be very large at all if it exists. There may be a handful of undiscovered planets actually. We just don't know. One as large as they were hypothesizing a few years ago would be amazing. But, I am quite sceptical.

Hmm, planet 9 is insulting to Pluto and this should be referred to as Planet X, as it always has been.  Seems woke scientists decided otherwise.

We can't see it because it is a black hole.

Hmmm,   Ya maybe …a small black hole could match the effects/influence of a large unseen planet? ,gravitationally, (which is what is causing their wonderment).

If its theoretical position was known the James Webb telescope could find it. If it is there.
