Planets beyond Neptune

[Priory_of_Sion]

The idea of large planets existing well beyond Neptune is no new idea, it has been around ever since Neptune was discovered. With Voyager 2's recalculation of Neptune's mass, the hunt for an extremely large "Planet X" dwindled away. 

 

Today, the story of that there might be a "Planet X" and even a "Planet Y" appears again, but this isn't something really out-of-the blue. Space is big, objects that don't emit light are dark, and telescopes only have certain attributes making them good for certain tasks. I have also seen too much claims that one of these planets is Nibiru(which the Sumerians never thought existed as a planet, more of a crossing point) or some other fanciful thinking.

 

Here is the abstract from the Scientific Paper: Link

 

This blog/podcast does a good job addressing much of the Planet X myths and realities among other topics. 

 

 

Also submit hypothetical planet names.

I still wish Nemesis existed.

I still wish Nemesis existed.

I never got the memo on how a brown dwarf could cause extinction events every 26 million years without doing some irreversible damage.

OK, so the NASA page on Dwarf planets states that planets proper are massive enough to clear out their own orbital paths, while dwarf planets are not.  Makes sense; the reason the astronomers think there's something there in the first place is that it's cleared out a path.

 

So, some super-big KBO?
