IRAS 16293-2422

IRAS 16293-2422 is a star-forming region. Around one of these young stars, which hasn't got a name yet, is a dust disk where the inner part rotates in the opposite direction than the outer part. It is quite reasonable that from this disk planets could form that will orbit in different directions. At least there is enough material in there.
Supposedly the star didn't evolve from one, but two gas clouds which counterrotated.

Constellation: Ophiuchus
Distance: 520 light-years
