The Outer Solar System Origins Survey released last month examined eight patches of the sky from 2013-2017, revealing the presence of more than 800 TNOs – but, after identifying eight TNOs that would be useful to test for a ninth planet, the researchers found no evidence of tight clustering.
This caused some to argue that biases in the data may be to blame for its supposed existence.
In the new study, the researchers from Complutense University of Madrid used a different approach for search for the mysterious planet, and they say it’s less susceptible to observation bias.
The team studied objects known as extreme trans-Neptunian objects, which are located at a distance more than 150 AU and never cross Neptune’s orbit.
The researchers found that the nodes of 28 ETNOs investigated in the study are clustered in particular zones.
They also found a correlation between the position of the nodes, and what’s known as inclination, a parameter for defining their orientation in space.
But, the researchers say, there should be no correlation between these factors.
‘Assuming that the ENTOs are dynamically similar to the comets that interact with Jupiter, we interpret these results as signs of the presence of a planet that is actively interacting with them in a range of distances from 300 to 400 AU,’ said de la Fuente Marcos.

It is a well-known fact that the presence of a massive perturber interacting with a population of minor bodies following very eccentric orbits can strongly affect the distribution of their nodal distances. The details of this process have been explored numerically and its outcome confirmed observationally in the case of Jupiter, where a bimodal distribution of nodal distances of comets has been found. Here, we show evidence for a possible bimodal distribution of the nodal distances of the extreme trans-Neptunian objects (ETNOs) in the form of a previously unnoticed correlation between nodal distance and orbital inclination. This proposed correlation is unlikely to be the result of observational bias as data for both large semimajor axis Centaurs and comets fit well into the pattern found for the ETNOs, and all these populations are subjected to similar background perturbations when moving well away from the influence of the giant planets. The correlation found is better understood if these objects tend to avoid a putative planet with semimajor axis in the range 300–400 au.

The idea of a rogue black hole that follows at a great distance from the Sun is fancy to me, but id imagine there'd be supernova remnants thatd show this.
From what Ive read, the idea is that a massive rocky planet is lurking out there.
That.....or the death star.

So many unknowns, so much to learn!

P.S. would be nice to see some academic sources for this, rather than freaking Daily Mail.
