Strange solar system bodies

[blobrana]

"Astronomers searching for distant supernovae to probe dark energy in the early universe have unwittingly stumbled upon two relatively nearby objects that may shed light on the early solar system.
One (2003 UC414 (http://cfa-www.harvard.edu/iau/lists/Centaurs.html)) lies in a nearly circular orbit between Uranus and Neptune, while the other (2004 VN112 (http://en.wikipedia.org/wiki/2004_VN112)) may have been kicked out to a much more distant, tilted orbit by a marauding planet that was lost to the solar system long ago."

Hahaha, it's Nemesis!

Nemesis is the hypothetical star.
Of the supposed 100 or so original (proto) planets in the early solar system, many were expelled entirely out of our system; however some earth or mars sized rogue planets could have found stable orbits on the outer fringes of the solar system.

That would be interesting

"An icy, unknown world might lurk in the distant reaches of our solar system beyond the orbit of Pluto, according to a new computer model.
The hidden world — thought to be much bigger than Pluto based on the model — could explain unusual features of the Kuiper Belt, a region of space beyond Neptune littered with icy and rocky bodies."
