A new dwarf planet has been discovered on the outskirts of the solar system. There are hints that a much larger perturbing body could be present - possibly upto 10 times the size of the Earth!
A planet of that size should have been apparent from its gravitational influence alone. How could we have missed such a giant planet in our own backyard, while we discover planets hundreds of lightyears away?
This is certain to fire up the Planet X / Nibiru conspiracists, providing some entertainment.
