Like I said, there is no need for you to participate in the thread if you don't like the topic for whatever reason, and I really don't need any
explanation from you for the reason of your hostility, just don't answer at all.
For anyone else actually interested in such data, here is another paper mentioning the unusual argument of perihelion close to 0 degrees of extreme
trans-Neptunian objects (ETNOs) which seems to indicate a large perturber, or perturbers in the outer reaches of the solar system.

Flipping minor bodies: what comet 96P/Machholz 1 can tell us about the orbital evolution of extreme trans-Neptunian objects and the production of
near-Earth objects on retrograde orbits

Nearly all known extreme trans-Neptunian objects (ETNOs) have argument of perihelion close to 0 degrees. An existing observational bias strongly
favours the detection of ETNOs with arguments of perihelion close to 0 degrees and 180 degrees yet no objects have been found at 180 degrees. No
plausible explanation has been offered so far to account for this unusual pattern. Here, we study the dynamical evolution of comet 96P/Machholz 1, a
bizarre near-Earth object (NEO) that may provide the key to explain the puzzling clustering of orbits around argument of perihelion close to 0 degrees
recently found for the population of ETNOs. Comet 96P/Machholz 1 is currently locked in a Kozai resonance with Jupiter such that the value of its
argument of perihelion is always close to 0 degrees at its shortest possible perihelion (highest eccentricity and lowest inclination) and about 180
degrees near its shortest aphelion (longest perihelion distance, lowest eccentricity and highest inclination). If this object is a dynamical
analogue (albeit limited) of the known ETNOs, this implies that massive perturbers must keep them confined in orbital parameter space. Besides,
its future dynamical evolution displays orbital flips when its eccentricity is excited to a high value and its orbit turns over by nearly 180 degrees,
rolling over its major axis. This unusual behaviour, that is preserved when post-Newtonian terms are included in the numerical integrations, may also
help understand the production of NEOs on retrograde orbits.
We do need more data to try to pin down exactly what is causing these anomalies, including the argument of perihelion being close to 0 degrees of
We are living in exciting times indeed.
