Evidence for planet X? (BBC)

"They detected evidence of 10 Jupiter-sized objects with no parent star
found within 10 Astronomical Units (AU). One AU is equivalent to the
distance between our Earth and Sun. Further analysis led them to the
conclusion that most of these objects did not have parent stars."

*Most* of the objects don't have a parent star. Which mean some or one did
have a parent star, i.e. was in an unusual orbit. Which star is within 10AU?
Only one is within light years (100,000s of AUs
http://en.wikipedia.org/wiki/Astronomical_unit) and that is the sun. So
translation:

'We have found a large planet in our solar system in an unusual orbit'???
