Astronomers have found a 200 kilometer wide object orbiting in a strange orbit, tilted 110 degrees to the plane of the solar system.

Niku travels against the flow of the bulk of the solar system, taking a wild backwards swing around the sun

could be related to planet 9!
another piece to solve the mystery!

It seems to fit along with the grouping other objects, hopefully it is related to planet 9 which I call "Terminus" But it is unlikely, perhaps this being in SE would be cool, mod?

steeljaw354, Did we discover what type of planet is that? Gas Giant? Ice Giant? Ice World? Titan? Or even a whole new type of planet? I'm so curious smile

200 kilometer wide

simonecinque1992, I guess it can be considered a big asteroid or a dwarf planet, it has 1/5 of the size of Pluto, so it definitely couldn't be a Gas Giant smile

Salvo,
Code

Oh, thanks. smile

Could it have moons? It is also 11 times smaller than Pluto.

Yes. Even many much smaller asteroids have moons [such asteroids are piles of rubble, so those moons could have formed in another way, though].

Could what we be seeing is actually 2 asteroids about half the same size orbiting around each other so close that isn't noticeable and hence we label it as one object?

I think that would be noticed quite quickly due to the Doppler effect, which is how it's usually detected when that situation occurs in binary stars.

Could we send a probe to it? It's backwards orbit certainly warrants investigation of the object

Sure, but unless the calculations are super-precise as to when to burn fuel and when and for how long, we won't see much. That is, unless NASA or whoever else may decide to start doing outer-solar-system missions, decide to splurge and go for an orbiter (which probably won't happen considering how much fuel it would take to slow down, the spacecraft would have to built in space like the ISS) An object 11 times smaller than Pluto would appear to zip by that much faster than Pluto did, hence lower-res pictures and less we can learn about it...It'd be best to use an orbiter for something like Niku, but hey, isn't that true for all the planets and dwarf planets, since they all have a unique story to tell?





Living among the stars, I find my way. I grow in strength through knowledge of the space I occupy, until I become the ruler of my own interstellar empire of sorts. Though The world was made for the day, I was made for the night, and thus, the universe itself is within my destiny.

Indeed, I would like to see orbiters of all Dwarf planets and odd objects like Niku and Sedna. Don't we all? It's unfortunate that we have to wait years to see images of these objects
