Let's suppose that Planet X is actually real and is a Neptune

You'd need a giant ship that can sustain life completely(gardens, oxygen, animals) using some renewable source of energy. It'd take a few generations of children before they got there.

OR

We'd have to perfect cryogenic stasis and revival.

You spelled "why" wrong.

What would it be like to live on a distant planet in darkness, surviving only on fusion and fission?

Geothermal would be developed first.

Whole expedition would have to take 5 years or less, of course.

At the moment the best way to assure the most minor amount of damage to your brain occurs is to remove the head from the body, or the brain from the body all together and freeze it with a fluid that will not form crystals.
In other words, we're quite far off from the form of cryogenics we would need for that sort of lengthy trip.
Unless we used a generation ship, which would mean you would need to assure enough biodiversity so that you don't up with too much consanguineous breeding and the resulting useless *retards (read: Habsburg).

It is plausible, though? I mean, not the meme evil Nemesis, but an actual planet found by measuring the motion of Neptune and Uranus, and actively searched right now.

Antimatter rocket and at least limited self fabrication. Also a way to put people into hibernation for prolonged periods of time. Maybe not real cryo but anything that stops the fuckers from squirming in the habitat wasting resources.

Well that's simply impossible based on current technology.

Wrong.

GFoi8ng there at all by any means is simply impossible using current technology. Current technology has nothing that will take a human above LOE, and past technology never had anything to go much beyond lunar orbit.

>about 600 AU from the Sun
An object that far away would be outside the heliosphere, right? Assuming it has a magnetosphere like the other giant planets, would it have aurorae? Would it even receive anything from the Sun other than light and heat?
