In their studies, the team analyzed the effects of what is called the Kozai mechanism, which is related to the gravitational perturbation that a large body exerts on the orbit of another much smaller and further away object. They looked at how the highly eccentric comet 96P/Machholz1 is influenced by Jupiter (it will come near the orbit of Mercury in 2017, but it travels as much as 6 AU at aphelion) and it may provide the key to explain the puzzling clustering of orbits around argument of perihelion close to 0° recently found for the population of ETNOs, the team wrote in one of their papers.
They also looked at the dwarf planet discovered last year called 2012 VP113 in the Oort cloud (its closest approach to the Sun is about 80 astronomical units) and how some researchers say it appears its orbit might be influenced by the possible presence of a dark and icy super-Earth, up to ten times larger than our planet.
This Sedna-like object has the most distant perihelion of any known minor planet and the value of its argument of perihelion is close to 0°, the team writes in their second paper. This property appears to be shared by almost all known asteroids with semimajor axis greater than 150 au and perihelion greater than 30 au (the extreme trans-Neptunian objects or ETNOs), and this fact has been interpreted as evidence for the existence of a super-Earth at 250 au. In this scenario, a population of stable asteroids may be shepherded by a distant, undiscovered planet larger than the Earth that keeps the value of their argument of perihelion librating around 0° as a result of the Kozai mechanism.

All clumps of rocks can get together, sing kumbaya, and call themselves “planets”. Except Pluto.

Is “Sedna” a real thing? or theorized..?

If I were in, ‘The Dating Pool’ these days, I’d just shoot myself in the head and save myself the trouble. ;)

Sedna is real. There are a few dwarf planets out there in the Kuiper belt that have been directly imaged.

That’s one reason why I do not go into the pool.

I’ve seen enough tattoo magazines to not even bother asking if that’s real. Why would anyone think that is a good idea?

Eris, Sedna, Haumea, and Makemake are the known Kuiper belt dwarf planets.

Not generally a fan of “ink” but impressive in more ways than one.

Well, maybe a few...
