This did sound really weird, so I confirmed it with John Anderson at
JPL. Anderson has been closely monitoring the positions of Pioneer
10 & 11 and Voyager 1 & 2 for several years, to see if a large body
(ie: 10th planet) would slightly tug on the spacecraft out of its
He did find a tug, but it was towards the Sun. And the
the extra tug was only observered in the spacecraft only,
and not in any of the other planets. That is the weird part, and
is why some people have described it is some kind of systematic error.
Nevertheless, Anderson is publishing his findings.
