I Can't Look At Sedna 90377's Orbit And Not Feel Lonely For It

Sedna 90377 is one of the many new "TNO"s or "trans-Neptunian objects". These objects are also often called "dwarf planets" but a more correct term would be "minor planets".
The scale of our universe, let alone our solar system is hard to wrap your head around. As human beings we simply cannot comprehend such distances. That being said, with how far away Sedna is from even far-off little Pluto, it's hard to not feel a tug on your heartstrings for the little orbital body.
Sedna is, for the most part, the furthest and darkest object in our solar system. It's named after the Inuit goddess of the arctic sea, who is said to live at the bottom of the ocean.
Currently, all other Sedna-like objects found are to be named for arctic deities. It is likely there are quite a few more way out there, so Sedna's probably not completely isolated.
Sedna's extreme orbit likely didn't happen out of the blue. Chances are, a large, at least Neptune-sized object is affecting the orbit of it and the other objects around it. This disruption is similar to the one Neptune caused on Uranus, which allowed us to discover Neptune using only mathematics.
Finding this "planet nine" with a similar method looks like a good idea, only this planet is so far away it's orbital path is absolutely gigantic. That's a lot of ground to cover!
