A popular press piece trying to cast doubt on the "new planet" is http://www.forbes.com/sites/startswithabang/2016/01/20/not-so-fast-why-there... I did not fully understand his objections, but he points out infrared surveys have been done that ought to have spotted such a big new planet, but didn't. Corrections: 1.LeVerrier and Adams had actually predicted Neptune, not Uranus. 2.The present prediction is considerably more sophisticated mathematically than the methods used by LeVerrier & Adams. He also mentions the existence of https://en.wikipedia.org/wiki/2008_KV42 which is a trans-neptune object that actually orbits the sun in the opposite direction to most everything else. Amazing. (And a few more such have been found too.) It is 50-90 km in diameter and its orbit takes 306 years. -- Warren D.
