All this explained away by adding a fraction of a percent in weight to
one of the outer planets?  That's about as logical as claiming a
slowing rotation on weather!

Astronomy magazine, Dec '81, discussion on Planet X
:: However, tiny Pluto is 100 to 1,000 times too small to fully 
:: account for Uranus' wobble, according to Thoman Van 
:: Flandern of the USNO.  A brief flurry of excitement, 
:: followed Charles Kowal's 1977 discovery of the planetoid 
:: Chiron, orbiting between Saturn and Uranus, until it was 
:: determined that it was too minute to be planet 10.  

Astronomy magazine, Oct '82, discussion on Planet X on page 62.  
:: Both Uranus and Neptune follow irregular paths that 
:: observers can explain only by assuming the presence 
:: of an unknown body whose gravity tugs at the two planets.
:: Astronomers originally though Pluto might be the body

Newsweek magazine, June 28 '82, a short article on page 83.  
:: A "dark companion" could produce the unseen force that 
:: seems to tug at Uranus and Neptune, speeding them up at 
:: one point in their orbits and holding them back as they pass.
::   ...  Anderson thinks the best bet is a dark star orbiting at 
:: least 50 billion miles beyond Pluto, which is 3.6 billion miles
